String Math 2021 - Simon Donaldson (Imperial College) - YouTube Hiraku Nakajima Robert A. Wilson, 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). Title: Langlands duality for 3-manifolds Organized by Mina Aganagic , Ivan Danilenko , Andrei Okounkov, and Peng Zhou. The powerpoint is here in powerpoint and here in pdf . 1. Abstract: This talk summarizes recent developments aimed towards F-theory constructions of MSSMs, i.e. 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). 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. Inspired by definitions of abstract (finite) groups and algebras and their linear actions, we introduce a framework for these symmetries in field theory. (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. NN-QFT Correspondence. Nikita Nekrasov This jargon sounds a bit confusing. To begin with, we'll discuss a few third-party libraries and their usage. The following articles by Carlip provide a nice overall perspective, drawing attention to the universality of BH entropy derived in different approaches to QG what he refers to as an embarrassment of riches. 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. Equivalent plumbing graphs suggest dual theories. The problem is not that its too new to be evaluated properly, but that its been a failure. This is exactly the place where you should be using eval(), or you will have to loop through the string and generate the numbers. 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. We propose that the matching of 5d coulomb branches plus the 2-group structure constants determined by the higher form symmetry of LSTs as criteria to predict heterotic T-dual candidates.The exploitation are generalized by picking non-trivial flat connections at the infinity to break E8 and Spin(32)/Z2 into their subgroups and confirm these T-dualities by the matching of criteria aforementioned. To address this issue, we use the fusion-matrix bootstrap, which is recently developed in the context of the light-cone bootstrap. Still, I think the best choice you can make is to use eval, given that you're able to trust the source of the string.

Abstract: Superconformal field theories with 8 supercharges in spacetime dimensions 3 to 6 have a large moduli space of vacua. [Slides]. Enter your email address to subscribe to this blog and receive notifications of new posts by email. This talk is based on joint work with Si Li. 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. We also provide the action of braiding on the relevant branes, so we can calculate Khovanov homology for any knot given its braid representation. I just work on Theoretical Physics topics. Title: Algebras and Entropies The match can be extended to saddles which appear in non-trivial Coulomb branch vacua. This feature could come in handy in projects where we want to evaluate math expressions provided in string format. Exactly because of this. how sensitive is the procedure to choice of k_mu he did the case where k_mu included a boost). These operators are interesting for several reasons: 3. String Math 2021 IMPA, Rio de Janeiro, June 14 - 18, 2021- Turned into an online event 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. W 2018 zostaa zaproszona jako wykadowczyni podczas Midzynarodowego Kongresu Matematycznego jest to jedno z najwaniejszych wyrnie dla matematykw. Math 302 (Vector Analysis and Integration on Manifolds) Spring 2021. String Math 2021 | IMPA - Instituto de Matemtica Pura e Aplicada We construct a trace map on the elliptic chiral homology of the free beta gamma-bc system using the BV quantization framework. 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. Why are Suriname, Belize, and Guinea-Bissau classified as "Small Island Developing States"? To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Philip Candelas With what result? Title: Bootstrapping AdS/BCFT Strings 2021 Summary Talk, So Paulo (June 21 - July 2, 2021) [on-line] . One can also Higgs chiral multiplets. [Slides] [Video], Davide Gaiotto (Perimeter Institute) In our examples we find agreement with the flux modularity conjecture of Kachru, Nally, and Yang. All, In this talk I will present how these two threads of research can be combined and what comes as a reward. 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: [Slides] [Video], Andrei Caldararu (University of Wisconsin Madison) Title: The character of M-theory Unit 3 - String, Math | APCS Finally, I will mention how some of these features are likely to persist in a proposal for the worldsheet dual of free N=4 Super Yang-Mills theory. Is a PhD visitor considered as a visiting scholar? 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. Asking for help, clarification, or responding to other answers. Based on joint work with Petr Kravchuk and Sridip Pal. Edward Witten (Institute for Advanced Study) . Weekly on Mondays 2:10 PM (Pacific Time) Meetings are in-person, at 402 Physics South. Finally, we will talk about the connections between the sphere packing problem and some mysteries of modern physics. Math Talks and Number Strings provide the foundation to help students improve their understanding and comprehension of numbers. Simon Donaldson The latter approach allows to realize holomorphically and topologically twisted field theories directly as worldvolume theories in deformed supergravity backgrounds, and we make extensive use of this. https://sites.google.com/unifi.it/scri21/program Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide. Im sorry if I cannot comment on other approaches to quantum gravity or non-stringy grand unification programs. Hello, Robert A. Wilson [Slides] [Video], Heeyeon Kim (Rutgers University) All, Likely Witten was thinking of things like the 6d (2,0) superconformal theory which has not classical limit and its construction is somewhat mysterious. ERIC - EJ1326337 - From Notes to Strings, Mathematics Teacher: Learning sqrt()) notations. I believe I am not misguided. 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). Staging Ground Beta 1 Recap, and Reviewers needed for Beta 2, Evaluate an Equation in Javascript, without eval(), Stand-in mathematical replacement for eval. In other physical contexts you have different symmetries than Poincare, often approximate symmetries. Katrin Wendland, Ron Donagi (University of Pennsylvania) Physically, flow treesprovide a mesoscopic representation of BPS states as nested multi-centered bound states of elementary constituents. Ivan Ip's Homepage - Hong Kong University of Science and Technology This public lecture is also a lecture in the Zapytaj fizyka series here is the lecture website. 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. If one neglects the mass term, they are formally homogeneous. CEIs are associated to an arbitrary Calabi-Yau category, together with a splitting of the Hodge filtration. Rio de Janeiro, RJ, CEP 22460-320, Brasil Abstract: I will be discussing my recent work [2110.08179] with Chris Blair and Dan Thompson on topology change in Poisson-Lie T-duality with spectators (i.e. and Physics), [G]Suman Kundu (Tata Inst. As an application, I will use conformal bootstrap techniques to obtain new rigorous bounds on the first positive Laplacian eigenvalue of hyperbolic orbifolds. This talk is based on joint work with Xenia de la Ossa, arXiv:2111.13221. UBC, Vancouver, Canada. This construction has several advantages and opens perspectives towards generalization to the case of the $cW$-algebras I just took a look at that session and thought one remarkable point was where people were asked what would cause you to give up on string theory? The only answers forthcoming were from Igor Klebanov, who said he had been working on it his whole life, so couldnt see himself giving up on it, and Ashoke Sen, who said he would only give up on it if it were shown to be mathematically inconsistent. Abstract: We discuss the partition functions of topologically twisted 5d SU(2) supersymmetric Yang-Mills theory on X x S1, where X is a smooth closed four-manifold. Update: In the final discussion section, Witten emphasizes that What is string theory? still has no answer, that we have little idea what it really is. A limit involving the quotient of two sums. Title: Integrability check for open quantum systems in Krylov Space Based on 2103.10271, 2111.07663 and upcoming work. Our starting point will be the observation that a rich source of discrete gauge symmetries in M-theory are Calabi-Yau threefolds with singularities that cannot be crepantly resolved. Follow In my talk, I will discuss the following two examples. 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). Using Hands-On Tools to Monitor Progress and Assess Students in Math. 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. Liouville theory appeared there under the form of a 2D Feynman path integral and since then has appeared in a wide variety of contexts (random conformal geometry, SUSY Yang-Mills, etc). Sat 3 Apr 2021 12.00 EDT Last modified on Tue 6 Apr 2021 09.54 EDT. Please, watch the discussions (there were many) and appreciate that these were honest discussion. PDF University of Shefeld & CNRS - University of California, Berkeley IMPA, Rio de Janeiro, June 14 - 18, 2021- Turned into an online eventSpeaker: Giovanni Felder (ETH Zrich)Lecture title: Superstring measure and the superper. StringStringBuilderStringBufferMath. String Math 2021 - Si Li (Tsinghua University) - YouTube 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. Even beginning PhD students will no longer believe that ST is the only framework that reproduces BH entropy. for Fundamental Research), [D] Juan Maldacena (Institute for Advanced Study), [T] Shiraz Minwalla (Tata Inst. We engineer these models using toric geometry techniques to construct non-compact threefolds that manifestly have multiple fibrations and hence M/F-theory lifts. 8. Breaking news: on July 5, 2022, Maryna Viazovska was awarded with the Fields medal, the highest recognition in mathematics! 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. Here's a quick basic example I came up with (updated (2011-06-26): cleaner w/ input boxes). From the README: Abstract: One aspect of the relation between physics and arithmetic geometry is the conjectured correspondence between supersymmetric flux vacua and weight-2 modular CY threefolds. Title: Vafa-Witten Theory: Invariants, Floer Homologies, Higgs Bundles, a Geometric Langlands Correspondence, and Categorification [online talk] Evaluating a Math Expression in Java | Baeldung A place where magic is studied and practiced? Dear Peter, @David Roberts: There are many references that discuss this from different perspectives. IMPA, Rio de Janeiro, June 14 18, 2021 Turned into an online event. 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. Title: Calculating Quantum Knot Homology from Homological Mirror Symmetry Title: Families of Modular Flux Vacua on Symmetric CY Threefolds Title: Magnetic quivers for Superconformal Field Theories Abstract: It has been found, originally in the context of black hole thermodynamics, that the concept of entropy is better-defined in the presence of gravity than in ordinary quantum field theory without gravity. 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. [Slides] [Video], Vincent Vargas (University of Geneva) 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. [Slides] [Video], Edward Witten (IAS) How do I check if an array includes a value in JavaScript? 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. 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. Whats really bizarre about the current situation is that string theory has completely decoupled from any well-defined proposal for an actual 3+1 d unified theory of gravity and the SM, while at the same time its proponents claim it is the only game in town. We then show the explicit duality between a specific form of correlators, the spectral form factor, and the Loschmidt echo with $hat{H}_{mathrm{mod}}$. 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? While the community just spread out to other problems. Can they make mistakes? We investigate a two-dimensional chiral analogue of the algebraic index theorem via the theory of chiral algebras developed by Beilinson and Drinfeld. TheamplituhedronAn,k,m(Z)is the image of the positive Grassmannian Grk,n0under a positive linear mapRnRk+m. We are going to perform a construction of such quantum curves using the mathematical language of vertex operator algebras. Lectures at St. Ottilien: Quantum Symmetries and K-Theory. Local nodes will be coordinated worldwide for the joint viewing of talks and discussion sessions, and online satellite meetings during other time periods will be linked on this webpage. 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. Dan Freed (University of Texas at Austin) In addition, distinct tensor branch data obtained from 6D theories with a single instanton inspire us to classify heterotic strings probing ADE singularities. ncdu: What's going on with this second size column? In other words, the string boundary conditions on the probe branes preserve the integrability of the corresponding Green-Schwarz sigma models. Symmetries, Horizons, and Black Hole Entropy [https://arxiv.org/abs/0705.3024] I could go on the whole night, but I believe, as most other string theorists do, there are more urgent or at least doable problems to solve now. Abstract: We implement the unitary equivalence of modular Hamiltonian $hat{H}_{mathrm{mod}}$ and Hamiltonian $hat{H}$,$hat{H}simhat{U}^{dagger}hat{H}_{mathrm{mod}}hat{U}$, to realize the emergence of time from an unitary operator $hat{U}$. Abstract: Recently, higher categorical understandings of quantum field theories have been rapidly developing. 3 years ago, F_K invariants of knot complements in 3-sphere have been proposed. String-Math, June 2013. Title: The sphere packing problem and beyond. One can add superpotentials, which lead to Seiberg-like dualities between plumbing graphs with triangles. There are other views, it is a matter of taste. Physical Review, 85(4), p.631. When the quiver comes from a smooth local toric Calabi-Yau 3-fold, we obtain a generalization of shifted Yangian, which acts on the cohomology of the moduli space of certain sheaves of the 3-fold. - rgbk21.

[Slides], Thorsten Schimannek (LPTHE Paris) Over-claim? Enjoy. Title: The positive Grassmannian, amplituhedron, and cluster algebras [online talk] It also gives one a feeling for how Arkani-Hamed works through problems. 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. String theorist Michio Kaku: 'Reaching out to aliens is a terrible idea 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.
