string math 2021

String theory calculations that can be done in unphysical situations (wrong dimension, lots of SUSY, extremal black holes) claim to reproduce the semiclassical limit. I think a better service to the public would be made by discussing things that are well established, rather that the permanent focus on what is coming/the future etc. Is there some function to create a simple calculator without eval. . This is damaging. 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. We revisit this construction, working directly in the setting of the holomorphically twisted theory and viewing the topological twists as further deformations. We investigate a two-dimensional chiral analogue of the algebraic index theorem via the theory of chiral algebras developed by Beilinson and Drinfeld. Matilde Marcolli People interested in string theory/LQG religious warfare argue about the calculations in 3. and 4. This provides an enumerative interpretation of the A-model topological string partition function on non-commutative resolutions of the singular Calabi-Yaus. Caltech's Feynman Centennial Symposium on 12 May 2018. While the community just spread out to other problems. Workshop on Categorification and geometric representation theory. What is the point of Thrower's Bandolier? Asking for help, clarification, or responding to other answers. AP Computer Science A 2021-22. Based on numerous works with G. Baverez, F. David, C. Guillarmou, A. Kupiainen, R. Rhodes. This approach is based on 2105.06039 and is joint work with Aganagic and Rapcak. Extending this story, I will talk about other physical realizations of analytically continued systems, such as Regge poles, replicas, or dimensional regularization. [Slides] [Video], Mirjam Cvetic (University of Pennsylvania) Abstract: I will discuss methods to numerically approximate Ricci-flat metrics for Calabi-Yau n-folds defined as complete intersections in toric ambient spaces. Requiring the unitary equivalence also implies Modular Chaos Bound = Chaos Bound''. You are possibly right its now pointless to debate those issues. The unitary equivalence relation implies a duality between the modular flow and time evolution. [Slides], Meng-Chwan Tan (National University of Singapore) There will also be a public lecture and outreach activity Ask a String Theorist during the weekend. I strongly disagree with you about the issue of the intellectual honesty of my account of what Witten and Arkani-Hamed had to say. CEIs are associated to an arbitrary Calabi-Yau category, together with a splitting of the Hodge filtration. Title: The sphere packing problem and beyond. In other words, the string boundary conditions on the probe branes preserve the integrability of the corresponding Green-Schwarz sigma models. and Physics), [G]Suman Kundu (Tata Inst. The Ryu-Takayanagi formula then encodes the fractal dimension of the boundary, while the extremal surfaces encode an important part of the geometry of the buildings, showing a new interplay between ideas from holography and geometric group theory. [Slides], Sam Gunningham (Montana State University) Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. The resulting quiver Yangians, together with their trigonometric and elliptic versions, unify various known results and generalize them to a much larger class. This construction gives rise to new quantum groups. Sakura Schafer-Nameki 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. Thats interesting, can you give pointers? Fd. I will also discuss a second application, a new definition of FJRW invariants in the presence of an arbitrary symmetry group. [Slides] [Video], Yaping Yang (University of Melbourne) This topic has been recently explored,from several differentperspectives,by Kontsevich-Soibelman and Doan-Rezchikov. I will then summarise recent work (with Matthias Gaberdiel and others) on the AdS_3/CFT_2 correspondence, in the tensionless limit, which gives a proof of concept of the above ideas. Abstract: I will discuss the theory of Dirac operators perturbed by the Coulomb potential in an arbitrary dimension. 2. What is a word for the arcane equivalent of a monastery? This community is indeed becoming like a religious cult, something one of the speakers explicitly denied. Title: Giant Gravitons in Twisted Holography In this tutorial, we'll discuss various approaches to evaluate a math expression using Java. 2013 Nov. Osaka City University, Japan. That would be something like (a real implementation will be somewhat more complex, especially if you consider the use of parenthesis, but you get the idea). NN-QFT Correspondence. I just had a look at that session, and more than anything, felt sorry seeing such eminent physicists giving such vacuous reasons just for the sake of defending a theory they have worked on for a long time. LQG calculations claim to reproduce the semi-classical limit. and finally I published a package on npm string-math. Can I tell police to wait and call a lawyer when served with a search warrant? Title: Magnetic quivers for Superconformal Field Theories [Slides] [Video], Nikita Nekrasov (Simons Center for Geometry and Physics) Little string theories also possess T-duality as well as higher form- and group symmetries. - rgbk21. -) and postfix (e.g. CICADAS [i.e. The CY manifolds admitting supersymmetric flux vacua can be associated to elliptic, Hilbert, or Bianchi modular forms, depending on the field the complex structure moduli of the CY take values in. In this talk, I will construct a large class of discrete geometric structures in all dimensions that satisfy these two properties, using the theory of hyperbolic buildings. In the presence of chiral multiplets that are added to plumbing graphs, we show that ST-transformations lead to many equivalent plumbing theories, and hence generalize the scope of Kirby moves. How is the idea that particles are irreducible representations of the Poincar group work in the context of quasiparticles in condensed matter physics, where the underlying system background is generally not symmetric under Poincar transformations (e.g. Yuji Tachikawa Mina Aganagic 1. Institutode Matemtica Pura e Aplicada (IMPA), Organizers: Henrique Bursztyn (IMPA), Reimundo Heluani (IMPA), Marcos Jardim (IMECC-UNICAMP), Gonalo Oliveira (UFF). Maryna Viazovska was awarded with the Fields medal, https://www.fuw.edu.pl/faculty-of-physics-home.html, Hera guesthouse of the University of Warsaw (budget option), https://warsawgenomics.pl/en/sars-cov-2/koronawirus-rtpcr. I will argue that they are encoded in the topological string partition functions of the singular Calabi-Yau itself and its various non-commutative resolutions. for Fundamental Research), [T] Sebastian Mizera (Institute for Advanced Study), [T] Sameer Murthy (Kings College London), [S] Hirosi Ooguri (Caltech and Kavli IPMU), [D] Joo Penedones (cole Polytech. In my view, this anxiety to communicate to the public the latest developments is a sign of certain immaturity. Probably not if you ask me. 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 . with the exact opposite agenda. 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. Za te oraz inne osignicia otrzymaa wiele prestiowych nagrd i wyrnie, m.in. This lecture is aimed for the general public and does not request much prerequisites in mathematics. Lectures at St. Ottilien: Quantum Symmetries and K-Theory. How to store objects in HTML5 localStorage/sessionStorage. Ironically, the very fact that he had to refer to it at all should alarm them. What is the !! I will illustrate this construction on examples of low rank 4d N=2 SCFTs. Motived by (twisted) holography (following Costello, Gaiotto, Li, and Paquette) we find a holomorphic model describing the minimal twist of the six-dimensional theory. Witten says something about a (possible) theory that is intrinsically quantum mechanical, which seems to mean a theory that does not start with a continuous field and quantise it, and which (therefore) presumably cannot be described in that way. Invertible QFTs are expected to form a sheaf of \infty-groupoids, and we apply the framework of differential cohomology to this sheaf. 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. How is Jesus " " (Luke 1:32 NAS28) different from a prophet (, Luke 1:76 NAS28)? (With exception of a group of very few dedicated researches, to whom I sincerely keep my deep respects.) Cookies and PrivacyAboutEventsNews More information can be found here Thematic trimester on vertex algebras: However, this is an unrealistically simple description of the situation, even for a basic example such as the classical phase space.. Check this JSBenchmark. There is also an open source implementation on GitHub, evaluator.js, and an NPM package. We present a novel construction of such flux vacua in permutation-symmetric multiparameter compactifications, and develop methods for efficiently computing the zeta functions of the corresponding geometries. [Slides] [Video], Maxim Kontsevich (IHS) Following Nimas final recommendation, an experimentalist and a string theorist hang out together. While Ooguri has his own interpretation about this observation (incoming flux of young people in the field is as healthy as ever), I wonder what others think about it. If one neglects the mass term, they are formally homogeneous. He notes that to get at non-perturbative string theory we seem to need some more general understanding of quantum theories, going beyond the usual quantization starting with an action, and ends by saying maybe quantum information theory can help. He discusses the swampland philosophy, but gives as a challenge to theorists just making more precise the sort of empty question that this philosophy deals in (he asks whether D=9 SU(2021) to the power 2021 is in the swampland). Can they make mistakes? Abstract: This talk summarizes recent developments aimed towards F-theory constructions of MSSMs, i.e. 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. Title: A holomorphic approach to fivebranes Fall 2021. Over-claim? Leszek Hadasz (Jagiellonian University) Green and Witten, recto and verso Another series of talks that I took a look at and that I can recommend is Nima Arkani-Hameds lectures on Physics at Future Colliders at the ICTP summer school on particle physics. Skeptical challenging of arguments is supposed to be what science is all about, but the speakers in this panel made it seem that this is absolutely not something that is part of their field or what they do. Go on and you certainly will be assured thats not going to be about qubits, Dear Robert. Title: Emergence of Time from Unitary Equivalence Abstract: Thepositive GrassmannianGrk,n0is the subset of the real Grassmannian where all Plcker coordinates are nonnegative. Adrian Langer 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. Only if the string comes from a trusted source. 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. 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. Since it's online only, talks are much more accessible than usual (and since it's free, over 2000 people have registered to in principle participate via Zoom). This includes joint work with David Ben-Zvi, David Jordan, Pavel Safronov, Monica Vazirani, and Haiping Yang. Abstract: I will explain how to explicitly calculate knot homology using the Fukaya category associated to a 2d Landau-Ginsburg theory, which is the equivariant mirror of the Coulomb branch of a 3d $mathcal{N}=4$ theory. I believe that your permanent opposing the string hypes is good and welcomed. Title: Holomorphic boundary conditions for topological field theories via branes in twisted supergravity This story also relates to the higher-form global symmetry. Nigel Hitchin (University of Oxford) The point though is that there are plenty of much simpler examples, which often can be understood purely in terms of representation theory. Title: BPSDendroscopyon local Calabi-Yau threefolds He goes on to explain the landscape philosophy, which he sees string theorists (and himself) as now adopting. Math 250 (Vector Analysis) . you see Ed Witten, and then Shiraz Minwalla, basically agreeing with you. Abstract: I will present some conjectures for higher-rank K-theoretic Donaldson-Thomas theory on toric three-folds, and some lessons that we learned from working equivariantly on non-compact spaces. [Slides], Ioannis Lavdas (LMU Munich) We will focus on understanding 3d mirror symmetry viachiralalgebras. 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. Hawking tells you what the semiclassical limit is. Yes, but I cant imagine that Witten was thinking of anything as well known and well understood as a qubit. [Slides] [Video], Mayuko Yamashita (Kyoto University) We can exhibit for instance a duality between a trivial bundle with abelian isometries and a non-trivial *bibundle* with a nonabelian Poisson-Lie group action. where the dualisable dimensions are fibred over a `spectator base). Talks are available for watching every day via Youtube, links are on the main page. Abstract: Homological block, commonly denoted by , is a 3-manifold invariant whose existence was predicted by S. Gukov, D. Pei, P. Putrov, and C. Vafa in 2017 using 3d/3d correspondence. As an application, I will use conformal bootstrap techniques to obtain new rigorous bounds on the first positive Laplacian eigenvalue of hyperbolic orbifolds. At the time I drop those lines, more than 50 years from dual resonance models?, I havent found any convincingly argument.

We introduce a new idea, boundary averaging, to address the question: Does averaging also work well in AdS/BCFT? I saw the discussions you refer to. commutative) spacetime case is well-known to yield the Yang-Mills(-Higgs) theory, namely almost-commutative manifolds, has to be replaced by its fuzzy counterpart already the classical level. Just like in the smooth case, one can ask about the multiplicities of BPS states that now carry an additional discrete charge. It fully encodes the geometry, and a simple algorithm allows access to the structure of nested singularities, which corresponds physically to a generalized Higgs mechanism.

Title: Towards F-theory MSSMs We determine the T-dual theories and match those global symmetries across the dualities. He never actually gets anywhere near discussing the topic of the title for the talks, but does give a very nice leisurely introduction to computing amplitudes for zero-mass particles. Theres a long list of things they are talking about under the name string theory, with the generic problem that the ones that are reasonably well-defined have nothing to do with the real world (e.g., wrong dimension). Dec 18, 2021 at 16:43. This is based on joint work with Raghavendran. W 2018 zostaa zaproszona jako wykadowczyni podczas Midzynarodowego Kongresu Matematycznego jest to jedno z najwaniejszych wyrnie dla matematykw. 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. https://sites.google.com/unifi.it/scri21/program 1 Let n be a natural number, n3. In other physical contexts you have different symmetries than Poincare, often approximate symmetries. The next String Math conference will take place on July 10-14, 2023, at the University of Melbourne in Australia. For different choices of superpotential, the LG theory categorifies the quantum knot invariants associated with any simply-laced Lie algebra. The string community has been dishonest for at least 20 years, and has absolutely no right to give any lessons about ethics in science. 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. The University of Warsaw The University of Warsaw, founded in 1816, is the largest university in Poland and a leading research centre in the country and in this region of Europe. (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. You will have to use the Number.isNaN() method to do it. In the case of rank one instantons this factors through a `Heisenberg type super Lie algebra and the story is analogous to Nakajimas action on the Hilbert scheme. I would be eager to read a real formal discussion if first-quantised RNS superstring in euclidean signature is quantum mechanically equivalent (unitary Boguliubov transformation) to original version starting from Minkowski signature. https://www.youtube.com/watch?v=WwmxaXTnGMI All, Postal Address:Instituto de Matemtica Pura e Aplicada To address the problem of quantization of a space with gauge fields, first the structure that in the smooth (i.e. , self-confidence, went through a Faustian-like monologue, if you allow me a little of prose: Ive studied, Schwarz, alas, Polchinski, Breaking news: on July 5, 2022, Maryna Viazovska was awarded with the Fields medal, the highest recognition in mathematics! 8.

If people think carrying on this argument is a good use of their time, they are encouraged to do so elsewhere. Title: Families of Modular Flux Vacua on Symmetric CY Threefolds Is it possible to create a concave light? Thanks for allowing my last comment. Abstract: The main goal of this talk is to present a novel conjectural incarnation of Langlands duality in the purely topological setting of character varieties of 3-manifolds and their quantizations via skein theory.
