The resulting quiver Yangians, together with their trigonometric and elliptic versions, unify various known results and generalize them to a much larger class. 1+ 2 *2' // 5 but ' 1 + +2* 2 ' // Error, This shows to be more performant than @vol7ron's solution. The video answered some questions that I still had (e.g. Thank you. This approach is based on 2105.06039 and is joint work with Aganagic and Rapcak. They have obvious applications to atomic physics. What hes doing is emphasizing ideas that are often not taught in conventional QFT courses (although they should be). I will also explain how the Hecke operators from geometric and analytic Langlands correspondence are realized in the four dimensional super-Yang-Mills theory. Progress in D=4, N=2 Field Theory, Strings-Math 2012, Bonn, July 2012 Powerpoint presentation here . How do I connect these two faces together? 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. Abstract: Three-manifold invariants $\hat Z$ (Z-hat), also known as homological blocks, are $q$-series with integer coefficients. Joerg Teschner (DESY) [Slides], Martin Bies (University of Pennsylvania) I will show how this calculation works for su(2) and give an example. ), one would at least expect that a well-behaved asymptotically perturbation series follows as one takes into account contributions from all the moduli parameters of Teichmller spaces of Riemann surfaces with higher genus and market points. Odbya stae podoktorskie na uniwersytecie Humboldta w Berlinie oraz uniwersytecie w Princeton w USA, a nastpnie zostaa profesorem w cole Polytechnique Fdrale de Lausanne (EPFL) w Szwajcarii, gdzie od 2018 roku kieruje Katedr Teorii Liczb. We show that many 3d theories can be represented as plumbing graphs and hence be able to be constructed by compactifying M5-branes on corresponding plumbing manifolds using the construction of 3d-3d correspondence. If youre so concerned about the public or physics community getting misled, surely youve contacted the organizers of and participants in the conferences Outreach activities. It seems that non-stringy approaches to quantum gravity are not very successful at reproducing these universal results. [Slides] [Video], Maxim Kontsevich (IHS) Im sorry if I cannot comment on other approaches to quantum gravity or non-stringy grand unification programs. How to format a number with commas as thousands separators? [Video], Hulya Arguz (IST Austria) A hyperbolic d-manifold gives rise to a Hilbert space which is a unitary representation of the conformal group in d-1 dimensions. General string perturbation theory using 2d conformal field theory. 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? You are either blinded or so convinced by the idea that string theory has nothing to say about Physics, that you pick any phrase that adds to your view of things. This gives the symmetry algebra action on the categorifiedDT. Title: Holomorphic boundary conditions for topological field theories via branes in twisted supergravity T-duality then becomes a fibre-base duality of the threefold which allows us to compute the little-string-charges directly from the Kac labels of the dual gauge groups. 2. crickets]. On the other hand, differential cohomology theories, whose relationships with physics are classical, are most modernly understood in terms of sheaves on manifolds with values in (\infty, 1)-categories. 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. Is there a way to calculate a formula stored in a string in JavaScript without using eval()? Anyway, truly bold attempt! [Slides], Aranya Bhattacharya (IISc, Bangalore) 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. How do I replace all occurrences of a string in JavaScript? We demonstrate the duality of quantum chaos quantities in the thermofield double state defined in a fermionic system. 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. Im posting this since I thought it could be useful for those very busy hep-ph physicists who may wish to go directly to (what I & surely many others) considers as the key moment from perspective lectures. 1. Math 435 (Differential Geometry) Fall 2020. [Slides], Elise LePage (University of California, Berkeley) 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. Francis (Skip) Fennell | Nov 3, 2021 . Title:Plumbing graphs with matter Title: Families of Modular Flux Vacua on Symmetric CY Threefolds But I believe that in todays update of this post you were not intellectually honest. [Slides] [Video], Nikita Nekrasov (Simons Center for Geometry and Physics) Only if the string comes from a trusted source. There will also be a gong show session of 5-minute talks by PhD students and a poster session using Zoom breakout rooms. Elements of this Hilbert space can be thought of as local operators living in a (d-1)-dimensional spacetime. 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. 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. 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.

Based on 2103.10271, 2111.07663 and upcoming work. I strongly disagree with you about the issue of the intellectual honesty of my account of what Witten and Arkani-Hamed had to say. Is a PhD visitor considered as a visiting scholar? The qubit example is a bit unfair since in some sense its the quantization of the sphere, although this sphere is not a classical limit of the quantum theory (and sphere isnt a cotangent bundle of some configuration space). Goodbye eval()! 5. The 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. Number Strings & Math Talk Routines for Grades 3-5. Explicit $q$-series form for $\hat Z$ is known for $SU(2)$ group, supergroup $SU(2|1)$ and ortho-symplectic supergroup $OSP(2|2)$. One can define correlation functions and derive conformal bootstrap equations constraining the spectrum. 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. The two-step procedure involves first finding points on the Calabi-Yau manifold and then approximating the Ricci-flat metric by approximating solutions to the underlying Monge-Ampere equation. Title: Geometry of Higher-Form Group Structures in String Theory Probably the best answer. Richard Thomas String theorist: indeed, whats QCD?. To address the problem of quantization of a space with gauge fields, first the structure that in the smooth (i.e. Strings 2021 will be held online during the two-week period June 21 July 2, 2021 from 9:30 15:00 in So Paulo (8:30 14:00 in NY, 14:30 20:00 in Paris). The point though is that there are plenty of much simpler examples, which often can be understood purely in terms of representation theory. [Slides], Meng-Chwan Tan (National University of Singapore) String Math Summer School. Title: Deriving Gauge-String Duality All major operations, constants, and methods are supported. Nigel Hitchin (University of Oxford) Knots and Natural Language. What is the point of Thrower's Bandolier? Well, that would be the case if people follow the hype for last 20-30 years or more. Ta strona wykorzystuje ciasteczka (cookies) w celu zapewnienia maksymalnej wygody w korzystaniu z naszego serwisu. -) and postfix (e.g. Correlation functions in the worldsheet theory on AdS_3 are shown to agree with those of the dual CFT_2, with both being given in terms of branched covers. Title: Elliptic trace map on chiral algebras A place where magic is studied and practiced? [Slides] [Video], Dalimil Mazac (IAS) 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. Edward Witten (Institute for Advanced Study) [Slides], Kasia Budzik (Perimeter Institute) [Slides] [Video], Edward Witten (IAS) If you are interested in what field theories Wittens probably interested in, then I certainly recommend you to follow the on going ICTSs Quantum Field Theory, Geometry and Representation Theory, with Wittens mini-course starting tomorrow: https://www.icts.res.in/program/qftgrt2021/talks, In order to get a feel what is at stake here, start with: The EMS prizes are always a good indication of future Fields medalists [Slides], Ioannis Lavdas (LMU Munich) Is String Theory a Theory of Nature? with the exact opposite agenda.. 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. With what result? [Slides], Sam Gunningham (Montana State University) Abstract: We will discuss how dualities of quantum field theories can be understood as analogous to Morita equivalences for algebras of various types. To address this issue, we use the fusion-matrix bootstrap, which is recently developed in the context of the light-cone bootstrap. String-Math 2021 conference (IMPA, Rio de Janeiro), [R = Review lecture] ; [D = Discussion session] ; [T = Research talk] ; [P = Public lecture] ; [S = Starting/Summary talks] ; [G = Gong-show talk]. Braces are not supported, am I right? Biogram (in Polish): Maryna Viazovska urodzia si, uczya i studiowaa w Kijowie w Ukrainie. 8. But this is just an opinion. Abstract: The six-dimensional superconformal field theory associated to an ADE Lie algebra plays a key role in the AGT correspondence. 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. The program is based on two main ingredients: The complex geometry of the underlying moduli spaces on the one hand, and cluster algebra structures defined by BPS- or DT-invariants on the other hand. @DKepler Title: Integrability check for open quantum systems in Krylov Space Can I tell police to wait and call a lawyer when served with a search warrant? Abstract: The sphere packing problem is a very natural geometric question and it has a long and exciting history. Sakura Schafer-Nameki Title: Vafa-Witten Theory: Invariants, Floer Homologies, Higgs Bundles, a Geometric Langlands Correspondence, and Categorification [online talk] I believe I am not misguided. It seems that no one in the string theory community dares to publicly breathe a word of skepticism. We have a lunch on the 4th floor of Physics South before the seminar. ncdu: What's going on with this second size column? Paraphrasing Fermat, I have discovered the ugly truth of this, which this margin is too narrow to contain. Nevertheless, it may be worthy registering on this blog some of those problems which arent enough emphasized. Title: Emergence of Time from Unitary Equivalence Strings 2021 Summary Talk, So Paulo (June 21 - July 2, 2021) [on-line] . This uses a combinatorial algorithm computing certain types of GromovWitten invariants encoded in a scattering diagram. Title: Categorical Enumerative Invariants Even beginning PhD students will no longer believe that ST is the only framework that reproduces BH entropy. Abstract: About 40 years ago J. Zinn-Justin formulated several conjectures about the perturbative expansion of the spectrum a quantum Hamiltonian (for the polynomial potential in 1 variable). Title: Knizhnik-Zamolodchikov revisited: (non)supersymmetric gauge theories, defects, and localization [Slides] [Video], Jan Dereziski (University of Warsaw) This lecture is aimed for the general public and does not request much prerequisites in mathematics. Title: Non-rational $widehat{su}(2)$ cosets and Liouville field theory Postal Address:Instituto de Matemtica Pura e Aplicada Sorry, but deleted various attempts to carry on the experimentalist vs. theorist mudfight of Ellis_AND_Wooster/Andr. In 2019, S. Gukov and C. Manolescu initiated a program to mathematically construct via Dehn surgery, and as part of that they conjectured that the Melvin-Morton-Rozansky expansion of the colored Jones polynomials can be re-summed into a two-variable series for knot complements. String Math 2021 - Si Li (Tsinghua University) 848 views Jun 15, 2021 27 Dislike Share Instituto de Matemtica Pura e Aplicada 100K subscribers The problem is not that its too new to be evaluated properly, but that its been a failure. The real stuff happens in physics without a press release, book, or blog. You, sir, are awesome. Certificates YouTube live YouTube playlist of the lectures The string community has been dishonest for at least 20 years, and has absolutely no right to give any lessons about ethics in science. Abstract: I will explain some recent and ongoing work on the state spaces associated to 3-manifolds in the Kapustin-Witten twists of 4d N=4 SYM. IMPA, Rio de Janeiro, June 14 - 18, 2021- Turned into an online eventSpeaker: Simon Donaldson (Imperial College)Lecture title: Calibrated geometry and gauge . This is joint work with Constantin Teleman and Greg Moore. 2. If people think carrying on this argument is a good use of their time, they are encouraged to do so elsewhere. It would differ in rare case, if this function evil() itself declared some variables which would want to be. This is damaging. IMPA, Rio de Janeiro, June 14 - 18, 2021- Turned into an online eventSpeaker: Giovanni Felder (ETH Zrich)Lecture title: Superstring measure and the superper. We also explain how these invariants and homologies will be categorified in the process, and discuss their higher categorification.

IMPA, Rio de Janeiro, June 14 18, 2021 Turned into an online eventSpeaker: Si Li (Tsinghua University)Lecture title: Elliptic chiral homology and quantum master equationEvent 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. @David Roberts: There are many references that discuss this from different perspectives. What does "use strict" do in JavaScript, and what is the reasoning behind it? 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). Abstract: This talk summarizes recent developments aimed towards F-theory constructions of MSSMs, i.e. Title: A Yang-Mills matrix theory We will explain how ideas from oriented matroids, tropical geometry, and cluster algebras shed light on the structure of the positive Grassmannian and the amplituhedron. Katrin Wendland, Ron Donagi (University of Pennsylvania) Piotr Kucharski (University of Amsterdam) and finally I published a package on npm string-math. 4. The match can be extended to saddles which appear in non-trivial Coulomb branch vacua. The hyperKahler branches can be characterized by a combinatorial object known as a magnetic quiver. 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. There will also be a public lecture and outreach activity Ask a String Theorist during the weekend. Green and Witten, recto and verso [Slides] [Video], Conan Leung (Chinese University of Hong Kong) I just work on Theoretical Physics topics. To begin with, we'll discuss a few third-party libraries and their usage. Abstract: Currently, there is a strong interest in the study of non-invertible symmetries of quantum field theories. Here's a quick basic example I came up with (updated (2011-06-26): cleaner w/ input boxes). 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. NN-QFT Correspondence. Moving away from such orbifold points requires generalizing the flow tree formula from the Abelian category of quiver representations to the derived category of the same. A limit involving the quotient of two sums. Go on and you certainly will be assured thats not going to be about qubits, Dear Robert. 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). Robert A. Wilson, David Morrison (University of California) Rio de Janeiro, June 18th, 2021. Ill explain this phenomenon, and propose a new effective algorithm for the calculation of the spectrum which is not based on quantum algebra at all (joint work in progress with A. Soibelman). and Physics), [G]Suman Kundu (Tata Inst. Why are trials on "Law & Order" in the New York Supreme Court? All, Unfortunately, finding explicit solutions to the system is a challenging problem due to the existence of an anomaly cancellation condition for the gauge fields. 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. How is Jesus " " (Luke 1:32 NAS28) different from a prophet (, Luke 1:76 NAS28)? This is based on joint work with Raghavendran. In this talk, I explain an ongoing work to combine them, and to give a higher relations between QFTs and differential cohomology.
