string math 2021

Home page of Greg Moore - Rutgers University Abstract: Liouville field theory was introduced by Polyakov in the eighties in the context of string theory. As Ive pointed out here before (cant find a link), theres nothing unusual about a quantum system that isnt just a conventional quantisation of a classical system. https://8ecm.si/prizes, Ashoke Sen has computed the logarithmic corrections to the Bekenstein-Hawking entropy of various standard black hole solutions in this paper. IMPA, Rio de Janeiro, June 14 - 18, 2021- Turned into an online eventSpeaker: Simon Donaldson (Imperial College)Lecture title: Calibrated geometry and gauge . Abstract: The spectrum of BPS states in D=4 supersymmetric field theories and string vacua famously jumps across codimension-one walls in vector multiplet moduli space. We also provide the action of braiding on the relevant branes, so we can calculate Khovanov homology for any knot given its braid representation. To address this issue, we use the fusion-matrix bootstrap, which is recently developed in the context of the light-cone bootstrap. Title: The Penrose Inequality as Swampland Condition? Title: Algebras and Entropies In response to the obvious question about relation to experiment and testability, people have clearly completely given up on this, with nothing to say (other than a bogus claim that string theory makes some prediction about B-mode polarization), going on about how it took thousands of years for the atomic hypothesis to be vindicated. [Slides], Mateo Galdeano (University of Oxford) Staging Ground Beta 1 Recap, and Reviewers needed for Beta 2, Evaluate an Equation in Javascript, without eval(), Stand-in mathematical replacement for eval. How to format a number with commas as thousands separators? How do I replace all occurrences of a string in JavaScript? I suppose I shouldnt have even let that get started. String Math 2021 - Si Li (Tsinghua University) - YouTube From this description, we propose a symmetry for the space of instantons on C^2 by an exceptional super Lie algebra called E(3|6). Thank you. Title: Liouville conformal field theory: from the probabilistic construction to the bootstrap construction It's december of 2021, and the java world has been rattled by a log4j vulnerability. PDF University of Shefeld & CNRS - University of California, Berkeley Probably the best answer. We introduce a new idea, boundary averaging, to address the question: Does averaging also work well in AdS/BCFT? The resulting quiver Yangians, together with their trigonometric and elliptic versions, unify various known results and generalize them to a much larger class. [Video], Hulya Arguz (IST Austria) and finally I published a package on npm string-math. Of course, these are people. Abstract: In this talk, I will revisit the construction of heterotic ALE instantons and the corresponding T-dual systems in 6D little string theories (LSTs). This is enabledby thesurprisingappearanceof a Penner-like matrix model whose spectral curve turns out to give a Strebel differential. In this talk, I will present a match between the large-N saddles of the correlation functions of determinants with semiclassical D-brane configurations in the dual theory, using a spectral curve construction. So, does anyone know about alternatives to eval()? They have obvious applications to atomic physics. Sheldon Katz (University of Illinois) Unit 3 - String, Math | APCS Dec 18, 2021 at 16:43. Boris Pioline (Universit Pierre et Marie Curie) To each 3-manifold equipped with a spin^c structure, is supposed to assign a q-series with integer coefficients that is categorifiable and provides an analytic continuation of the Witten-Reshetikhin-Turaev invariants. Shing-Tung Yau (Harvard University), The interpretation of semiclassical gravity as an average of CFTs has provided much progress in understanding the factorization problem and the information paradox. If you want to be added to the seminar mailing list, use this link https . We focus on $\hat Z$ for $SO(3)$ group and orthosymplectic supergroup $OSP(1|2)$. with the exact opposite agenda. But what DUNE will find has been predicted years ago: normal neutrino mass order, no additional neutrinos, no proton decay, and no physics beyond the standard model whatsoever. This finding suggests that the dual domain wall systems are integrable to all loop orders and for any value of the bond dimension. IMPA, Rio de Janeiro, June 14 18, 2021 Turned into an online event. Strings 2021 started today, program is available here. Interestingly, most of the structures uncovered have a fractal boundary at infinity, which possesses a rich geometric structure. Webinars - hand2mind In my talk, I will discuss the following two examples. Green and Witten, recto and verso Probably not if you ask me. In two dimensions, thesebounds allow us to determine the set of first eigenvalues attained by all hyperbolic orbifolds. Title: Non-rational $widehat{su}(2)$ cosets and Liouville field theory Infinite Analysis 13 Autumn School on Quantum Dilogarithm, Modular Double, and Representation Theory. In this case, because the string is assumed to be safe and trusted, we would expect use of either eval() or the Function constructor to be reasonable. Make an operation based on string, including priority for multiplication and division with vanilla javascript and nodejs. Poor fool that I am, Abstract: We revisit Vafa-Witten theory in the more general setting whereby the underlying moduli space is not that of instantons, but of the full Vafa-Witten equations. NN-QFT Correspondence. Nikita Nekrasov Also I explain what is the dimension for a mathematician and why it is an extremely useful concept for everyone. Title: Langlands duality for 3-manifolds String Math 2021 | Clay Mathematics Institute Knots and Natural Language.

String theorist Michio Kaku: 'Reaching out to aliens is a terrible idea Abstract: Gauge-String duality(or the AdS/CFT correspondence, as a special case) has wide ranging ramifications in physics as well as mathematics. Chrome's Content Security Policy will still throw EvalError, Creating constructor doesn't make sense here and it takes unnecessary resources. In particular, we provide two different path integral derivations of their wall-crossing formula for b_2^+(X)=1. What hes doing is emphasizing ideas that are often not taught in conventional QFT courses (although they should be). How do I connect these two faces together? The video answered some questions that I still had (e.g. As Peter keeps on repeating, the denial of the string community to acknowledge the failure of string theory as a unification theory (which is nothing to be ashamed off: physics is full of beautiful theory that are not correct) is a shame for the physics community. Title: Knizhnik-Zamolodchikov revisited: (non)supersymmetric gauge theories, defects, and localization Abstract: Cosmic censorship as a conjecture about classical General Relativity is now understood to be false in both higher dimensional asymptotically flat space and four-dimensional AdS. Math Talks and Number Strings provide the foundation to help students improve their understanding and comprehension of numbers. Joerg Teschner (DESY) Ta strona wykorzystuje ciasteczka (cookies) w celu zapewnienia maksymalnej wygody w korzystaniu z naszego serwisu. Enjoy, This solution also clips whitespaces and checks for duplicating operators, e.g. ' [Slides] [Video], Mayuko Yamashita (Kyoto University) Besides reviews of major developments in the field and specialized talks on specific topics, an important novelty will be several informal discussions involving two researchers and the conference participants. What video game is Charlie playing in Poker Face S01E07? Based on 2103.10271, 2111.07663 and upcoming work. We study an open quantum many body spin system to check whether its integrable and chaotic regimes can be distinguished by looking at the non-unitary dynamics of a simple operator in Krylov space. [Slides]. Abstract: Three-dimensional N =4 supersymmetric field theories admit a natural class of chiral half-BPS boundary conditions that preserve N = (0, 4) supersymmetry. This lecture is aimed for the general public and does not request much prerequisites in mathematics. Our brane engineering approach combines the intersecting brane configurations of HananyWitten with recent work of Costello and Li on twisted supergravity. Off topic, but the European congress of Mathematics has finished up. In this talk, we will explain how to compute concrete equations of mirrors to blow-ups of toric varieties in the framework of the GrossSiebert program. Nevertheless, from a theory claiming to be the only mathematically self-consistent unification program, something regarded as just a mere technicality now requires an answer. [Slides]. Abstract: Open quantum systems are of experimental interest since ideally real life experiments always have some interaction with its environment. Using Hands-On Tools to Monitor Progress and Assess Students in Math. Abstract: During my presentation, I will discuss certain equivalences between conformal field theories with a continuous spectrum: Liouville theory, its supersymmetric extension, and models based on the affine su(2) algebra with irrational level. I will present recent progress in this direction in the simplest case of local $P^2$, and argue that its global BPS spectrum and flow tree structure can be deduced from a scattering diagram with simple initial data. Our conjecture, which we have developed with Ben-Zvi, Gunningham and Safronov, asserts an equality of dimensions between the G- and G^L-skein modules of a 3-manifold at generic quantization parameter. Weekly on Mondays 2:10 PM (Pacific Time) Meetings are in-person, at 402 Physics South. I agree with Felix. We have a lunch on the 4th floor of Physics South before the seminar. [Slides]. Just viewed the last question and answer session. Physics Meets AI, LMU Munich, September 2020. Dan Freed (University of Texas at Austin) Its explicit description as a QFT has remained elusive. IMPA, Rio de Janeiro, June 14 18, 2021 Turned into an online eventSpeaker: Mina Aganagic (UC Berkeley)Lecture title: Knot homologies from mirror symmetryEvent page: http://bit.ly/stringmath2021Videos playlist: https://bit.ly/3v2lHlsThe series of String-Math conferences has developed into a central event on the interface between mathematics and physics related to string theory, quantum field theory and neighboring subjects. Everything is in the description. Nigel Hitchin (University of Oxford) Brittany Goerig | Oct 14, 2020 | 00:56:54. Evaluator.js is used by a desktop calculator application of the same name. The conference String-Math 2021 which was supposed to be held at IMPA, will be online due to the current pandemic. The String Math series of conferences have become an important eventfor anyone working at the interface between mathematics and theoretical physics (string theory, quantum field theory and adjacent topics), bringing together an interdisciplinary cohort of pure mathematicians and theoretical physicists. In this talk, we will discuss recent progress in constructing explicit examples of higher-categories describing non-invertible symmetries in quantum field theories of various spacetime dimensions ranging from d=3 to d=6. CICADAS [i.e. Institutode Matemtica Pura e Aplicada (IMPA), Organizers: Henrique Bursztyn (IMPA), Reimundo Heluani (IMPA), Marcos Jardim (IMECC-UNICAMP), Gonalo Oliveira (UFF). Not the answer you're looking for? TheAttractor Flow Tree conjecture postulates that the BPS index $\Omega(\gamma,z)$ for given charge $\gamma$and moduli $z$ can be reconstructed from the`attractor indices $\Omega_*(\gamma_i)$ counting BPS states of charge $\gamma_i$ in their respective attractor chamber, by summing over all possible decompositions $\gamma=\sum_i \gamma_i$ and over decorated rooted flow trees. In particular, he discovered a hidden structure governed by Bernoulli numbers. Davide Gaiotto I am currently reading Weinbergs book to fill some holes in my knowledge. fiendish mathematics and mind-boggling . Title: Quantum curves and vertex algebras While such boundary conditions are not compatible with topological twists, deformations that define boundary conditions for the topological theories were recently introduced by Costello and Gaiotto. This goes without saying all technically challenging fundamentally important problems required for superstring theory unification be at least mathematically self-consistent have been left unanswered. With what result? Abstract: We explore little string theories in six dimensions, constructed via F-theory that are dual to heterotic stringswith NS5 branes probing ADE type singularities. One can also Higgs chiral multiplets. CEIs should be thought of as a precise realization of the general idea, due to Kontsevich, that the category of open strings (plus data of the splitting) determine closed string invariants. [Slides] [Video], Boris Pioline (Sorbonne Universit and CNRS) This is based on arXiv:2202.01788, with Matilde Marcolli and Sarthak Parikh. Strona gwna - Stringmath2022 Really amazing work! People interested in string theory/LQG religious warfare argue about the calculations in 3. and 4. It is expected that the right mathematical structure to capture physical properties of such symmetries is that of higher-categories. lectures on Physics at Future Colliders at the ICTP summer school on particle physics, talk on Connecting String Theory to the Real World We See Outside Our Windows, https://sites.google.com/unifi.it/scri21/program, https://www.youtube.com/watch?v=WwmxaXTnGMI, https://www.youtube.com/watch?v=hk_6EtWUatM. Title: The higher dimensional tropical vertex Title: q-series for so(3) and osp(1|2) This community is indeed becoming like a religious cult, something one of the speakers explicitly denied. If one neglects the mass term, they are formally homogeneous. Of course there are many ways to obtain the BH formula that do not try to identify the microscopic degrees of freedom in a theory of QG, the original calculation from the 70s being an obvious example. Title: Holomorphic boundary conditions for topological field theories via branes in twisted supergravity This is damaging. Clay Mathematics Institute, ContactEnhancement and Partnership ProgramMillennium Prize ProblemsPublicationsHome. This will be done in the language of QP manifolds/symplectic L-infinity algebroids which is convenient for showing the duality is a canonical transformation in string phase space, and also provides glimpses of a generalisation towards U-duality and higher branes. Evaluator.js is a small, zero-dependency module for evaluating mathematical expressions. David Ben-Zwi Abstract: I will discuss methods to numerically approximate Ricci-flat metrics for Calabi-Yau n-folds defined as complete intersections in toric ambient spaces. I will discussa phenomenon similar to Frobenius of modular representation theory. There will also be a public lecture and outreach activity Ask a String Theorist during the weekend. 2021-22. In the discussion section, Vafa challenges him on this, saying he sees no indication that quantum information theory gives any insight into dualities he sees as the central aspect of the non-perturbative theory. that perturbation series following from superstring S-matrix, already known to diverge as one sums over all moduli parameters (which isnt really the issue, since this happens even in QED, see Dyson, F.J., 1952. As you probably guess from my former comments under the present pseudonym, Im one of those students whom, maybe for lacking courage or ,who knows? Strings 2021 | Not Even Wrong - Columbia University Chen-Te Ma (Asia Pacific Center for Theoretical Physics) Hawking tells you what the semiclassical limit is. Divergence of perturbation theory in quantum electrodynamics. Mina Aganagic Title: Calculating Quantum Knot Homology from Homological Mirror Symmetry Author: Online2PDF.com Created Date: 2. In other words, a ternary string is a n-permutation with a repetion of the set {0,1,2}. Jim Halverson I will then explain how to describe their representations using subcrystals and how they can be translated into the framings of the quivers. In my view, this anxiety to communicate to the public the latest developments is a sign of certain immaturity. The LQG example hardly qualifies if you do not have any way to fix the Immirzi parameter and just tune it to get the desired result. Why are Suriname, Belize, and Guinea-Bissau classified as "Small Island Developing States"? More information can be found here Thematic trimester on vertex algebras: (ii) Every-time I receive a grant report asking for resources, penned by a senior string theorist, Im already able to guess the 1st lines: ST is the only mathematically consistent candidate for understanding quantum gravity while providing a framework potentially unifying all know fundamental interactions. Abstract: I will discuss the theory of Dirac operators perturbed by the Coulomb potential in an arbitrary dimension. [Slides], Alex S. Arvanitakis (Vrije Universiteit Brussel) Unfortunately, finding explicit solutions to the system is a challenging problem due to the existence of an anomaly cancellation condition for the gauge fields. Caltech's Feynman Centennial Symposium on 12 May 2018. with the exact opposite agenda.. StringStringfinal . [Slides] [Video], David Jordan (University of Edinburgh) Starting from 1h14m of this meet the public vide Recently, a rigorous probabilistic construction of the path integral was provided using the Gaussian Free Field. It also gives one a feeling for how Arkani-Hamed works through problems. The problem with the string theory hype is not that its new, exciting, cutting-edge speculation, rather than well-established. (videos of the talks at the bottom). One can define correlation functions and derive conformal bootstrap equations constraining the spectrum. The nature of simulating nature: A Q&A with IBM Quantum researcher Dr. Jamie We've added a "Necessary cookies only" option to the cookie consent popup. Inspired by definitions of abstract (finite) groups and algebras and their linear actions, we introduce a framework for these symmetries in field theory. Even without LQG, there are many ideas on/in QG which are physically well founded. For a so called well defined mathematical theory, cannot be tweaked etc, the number of unsolved issues with it and the claim not understanding what string theory is is inconsistent. We introduce a. new idea, boundary averaging, to address the question: Does averaging also work well in AdS/BCFT? I watched the entire video on the Poincare group and, although the path was the same as Weinberg, there was a lot of new information I thought it was excellent. Marlborough School. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. You can sanitize the string with a regex first to be safe: If you wanted another method, you'd have to use a pure Javascript implementation of the exact thing eval is going to do. I just work on Theoretical Physics topics. In this talk I will present how these two threads of research can be combined and what comes as a reward. In the limit of large covering, we arrive at an even more fine grained picture and see how the moduli space of string worldsheets arises fromthe dual CFT. [Slides] [Video], Fabian Ruehle (Northeastern University) I did watch fully the discussions I wrote about here, also took a look at many of the others. I will then outline work in progress with Gunningham and Safronov to prove the conjecture in a number of special cases. StringStringBuilderStringBufferMath. In this talk, I will explain how to prove their conjecture for a big class of link complements by making use of the R-matrix for Verma modules. Abstract: Knizhnik-Zamolodchikov equation, originally found in the context of a two dimensional conformal field theory, has recently been found in the context of instanton counting, albeit with a significantly extended domain of allowed parameters (level, spins etc). We engineer these models using toric geometry techniques to construct non-compact threefolds that manifestly have multiple fibrations and hence M/F-theory lifts. Announcement String Math 2022 Lorenz Eberhard(IAS) String correlators on AdS3 17:00 - 17:50 14:00 - 14:50 Melissa Liu(Columbia University) Wall-Crossing for the Mirror Quintic . In our examples we find agreement with the flux modularity conjecture of Kachru, Nally, and Yang. We will focus on understanding 3d mirror symmetry viachiralalgebras. (UoS & CNRS) Quantum G & of Looijenga pairs Berkeley String-Math 2021 Overview The two main messages: 1ve (different, but equivalent) string-theory motivated enumerative theories built from (X;D) 2they are all closed-form solvable Joint with P. Bousseau (ETH Zrich/Saclay) and M. van Garrel (Warwick/Birmingham). String Math 2021, held online by IMPA, Rio de Janeiro, Rio de Janeiro, June 14 - 18, 2021. The way I see the string people (not necessarily those who appear in the media, but those who publish in the arXiv) is as a small set of honest and hard working physicists, technically sophisticated, researching mostly on QFT and Gravity, with various approaches. Discrete mathematics - ternary strings. - Mathematics Stack Exchange A ternary string is a sequence of n symbols that has some of the digits 0, 1, 2. Hello, Robert A. Wilson Abstract: The D3-D5 and D2-D4 probe-brane systems with nonzero worldvolume flux are holographically dual to N=4 super Yang-Mills and ABJM theory in the presence of half-BPS domain walls. Quantum gravity: String theory is a theory of quantum gravity because it attempts to merge quantum physics with the theory of general relativity. This is a joint work with K. Ohmori (U. Tokyo). The only message I hear repeatedly is that String theory is the only game in town. AP Computer Science A. What is the point of Thrower's Bandolier? The LQG derivation, involving an ad-hoc choice for the Immirzi parameter In other physical contexts you have different symmetries than Poincare, often approximate symmetries. Thanks for contributing an answer to Stack Overflow! Title: Automorphic Spectra and the Conformal Bootstrap [Slides]. The string community has been dishonest for at least 20 years, and has absolutely no right to give any lessons about ethics in science. String theory is now older than not just my students, but also many of their parents and unfortunately its very well-established, sometimes even taught to high school students. Notes (with animations), Video. All major operations, constants, and methods are supported. There is also an open source implementation on GitHub, evaluator.js, and an NPM package. . This relation originally developed from the point of view of matrix models, was later studied from the point of view of conformal field theory. There are other views, it is a matter of taste. Making statements based on opinion; back them up with references or personal experience. The linking numbers of plumbing graphs are interpreted as the effective mixed Chern-Simons levels of 3d N=2 theories with chiral multiplets. Do roots of these polynomials approach the negative of the Euler-Mascheroni constant? In particular, i can not find a derivation of any black hole entropy from first principles in quantum gravity outside of string theory. Workshop on Categorification and geometric representation theory. Leonardo Rastelli Robert A. Wilson, [Slides] [Video], Vincent Vargas (University of Geneva) Robert A. Wilson, Title: Dirac-Coulomb Hamiltonians[online talk] Fall 2021. We provide significant evidence that averaging plays an important role in reproducing. I will also discuss a second application, a new definition of FJRW invariants in the presence of an arbitrary symmetry group. Abstract:We discuss abelian 3d N=2 theories T[,U(1)] engineered by plumbing manifolds . These models share the general structure of the so-called canonical LG-models; constructed by Marsh, Pech, Rietsch and Williams for Grassmannians, Lagrangian Grassmannians and quadrics, and we will discuss our ongoing efforts in unifying the models into a type-independent canonical model. [Slides], Thorsten Schimannek (LPTHE Paris) [Slides] [Video], Sunghyuk Park (California Institute of Technology) This talk is based on joint work with Si Li. CRM, Montreal, Canada. Sorry, but deleted various attempts to carry on the experimentalist vs. theorist mudfight of Ellis_AND_Wooster/Andr. Explicit $q$-series form for $\hat Z$ is known for $SU(2)$ group, supergroup $SU(2|1)$ and ortho-symplectic supergroup $OSP(2|2)$. Anyway, truly bold attempt! It is healthy. Katrin Wendland, Ron Donagi (University of Pennsylvania) Thats about the general problem of quantizing a symplectic manifold, but my impression was that Witten was thinking of the even more general problem of a quantum theory with no known symplectic manifold of which it is the quantization. Strings provided the authors with a way to make relatively small changes to guided notes in algebra 1, algebra 2, precalculus, and AP calculus classes. String Math Summer School. This is joint work with Constantin Teleman and Greg Moore. We highlight prototype examples of elliptically fibered non-compact Calabi-Yau fewfolds and comment on the fate of these symmetries when these spaces become compact. Physical Review, 85(4), p.631. Finally, I will discuss some applications. Reimundo Heluani Organizing Committee. We physically derive (i) a novel Vafa-Witten four-manifold invariant associated with this moduli space, (ii) their relation to Gromov-Witten invariants, (iii) a novel Vafa-Witten Floer homology assigned to three-manifold boundaries, (iv) a novel Vafa-Witten Atiyah-Floer correspondence, (v) a proof and generalization of a conjecture by Abouzaid-Manolescu about the hypercohomology of a perverse sheaf of vanishing cycles, (vi) a Langlands duality of these invariants, Floer homologies and hypercohomology, and (vii) a quantum geometric Langlands correspondence with purely imaginary parameter that specializes to the classical correspondence in the zero-coupling limit, where Higgs bundles feature in (ii), (iv), (vi) and (vii).
