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. Certificates YouTube live YouTube playlist of the lectures Additionally, Evaluator.js intelligently reports invalid syntax, such as a misused operator, missing operand, or mismatched parentheses. 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. Abstract: I will review the Cohomological Hall algebra associated to a quiver and an oriented cohomology theory. I strongly disagree with you about the issue of the intellectual honesty of my account of what Witten and Arkani-Hamed had to say. . Sakura Schafer-Nameki (i) No one convincingly proved the mathematical equivalence between the RNS superstrings and GS formalism. Starting from 1h14m of this meet the public vide rotations and translations are typically discretized due to the presence of a lattice)? What is the !! I am currently reading Weinbergs book to fill some holes in my knowledge. The point though is that there are plenty of much simpler examples, which often can be understood purely in terms of representation theory. 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. Abstract: This talk summarizes recent developments aimed towards F-theory constructions of MSSMs, i.e. The EMS prizes are always a good indication of future Fields medalists To summarize the situation, now as it has ever been: 1. 2014 June. Here is an implementation of the Shunting-yard algorithm with additional support for unary prefix (e.g. Just like in the smooth case, one can ask about the multiplicities of BPS states that now carry an additional discrete charge. Math 302 (Vector Analysis and Integration on Manifolds) Spring 2021. Abstract: Three-manifold invariants $\hat Z$ (Z-hat), also known as homological blocks, are $q$-series with integer coefficients. [Slides] [Video], Andrei Caldararu (University of Wisconsin Madison) [Slides], Sachin Chauhan (Indian Institute of Technology, Bombay) 1+ 2 *2' // 5 but ' 1 + +2* 2 ' // Error, This shows to be more performant than @vol7ron's solution. 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. In other words, the string boundary conditions on the probe branes preserve the integrability of the corresponding Green-Schwarz sigma models.

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. 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. During professional development, the authors learned about strings--a powerful instructional routine used in elementary classrooms to elicit students' mental mathematics strategies and use those strategies to build conceptual understanding. 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). 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. , self-confidence, went through a Faustian-like monologue, if you allow me a little of prose: Ive studied, Schwarz, alas, Polchinski, 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. Paul-Konstantin Oehlmann (Uppsala University) [Slides], Carlos Perez-Sanchez (University of Heidelberg) 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). Once again, this is just an opinion. How to check whether a string contains a substring in JavaScript? 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. -) and postfix (e.g. In the end, we also consider a two-qubit system to demonstrate that a different entanglement spectrum does not provide the same constraint to $hat{H}$. 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. I suppose I shouldnt have even let that get started. Pyry Kuusela (University of Oxford) how sensitive is the procedure to choice of k_mu he did the case where k_mu included a boost). 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. 3. Ironically, the very fact that he had to refer to it at all should alarm them. 1 Let n be a natural number, n3. Title: Non-Invertible Symmetries and Higher-Categories AP Computer Science A 2021-22. 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 $hat{U}$. So, does anyone know about alternatives to eval()? Abstract: Thepositive GrassmannianGrk,n0is the subset of the real Grassmannian where all Plcker coordinates are nonnegative. 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 revisit this construction, working directly in the setting of the holomorphically twisted theory and viewing the topological twists as further deformations. Is a PhD visitor considered as a visiting scholar? A ternary string is a sequence of n symbols that has some of the digits 0, 1, 2. Abstract: The theory of Categorical Enumerative Invariants (CEIs) is a non-commutative generalization of the theory of Gromov-Witten invariants. I will then outline work in progress with Gunningham and Safronov to prove the conjecture in a number of special cases. Just viewed the last question and answer session. Yes, I was ignoring some other things they had to say, for example, Arkani-Hameds Finally, we will talk about the connections between the sphere packing problem and some mysteries of modern physics. Title: Quantum duality and Morita theory for chiral algebras [online talk] Nothing will be said about multiverses or swampland on what follows. 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. A better version was given September 22, 2021 at Yan Soibelman's M-seminar. 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. In particular, he discovered a hidden structure governed by Bernoulli numbers. [Slides] [Video], Sunghyuk Park (California Institute of Technology) Abstract: Currently, there is a strong interest in the study of non-invertible symmetries of quantum field theories. 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. In 2016 the speaker was lucky enough to solve the sphere packing problem in dimension 8 and contribute to its solution in dimension 24. Please, do appreciate that negative comments like yours distort the ideas the general public (or even physicists in other areas) have about String Theory, or Theoretical Physics in general. 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. Title: q-series for so(3) and osp(1|2) Exactly because of this. Depending on the coupling constant and dimension, they exhibit several distinct scaling behaviors (or if you prefer the high energy jargon, various renormalization group flows). Abstract: I will describe a close analogy between the spectral geometry of hyperbolic manifolds and conformal field theory. [Slides] [Video], Dalimil Mazac (IAS) Title: On topology change in Poisson-Lie T-duality and Physics), [G]Suman Kundu (Tata Inst. This topic has been recently explored,from several differentperspectives,by Kontsevich-Soibelman and Doan-Rezchikov. Hope you will find them as a useful starting point. Others clearly feel differently and think this is of huge significance. Philip Candelas This community is indeed becoming like a religious cult, something one of the speakers explicitly denied. However, this is an unrealistically simple description of the situation, even for a basic example such as the classical phase space.. Update: At String 2021, yesterday Nima Arkani-Hamed gave a talk on Connecting String Theory to the Real World We See Outside Our Windows, where he sometimes sounds like me, contrasting the pre-LHC claims of string theorists: 1. 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. Enter your email address to subscribe to this blog and receive notifications of new posts by email. Green and Witten, recto and verso This talk is based on joint work with Si Li. [Slides] [Video], Davide Gaiotto (Perimeter Institute) We introduce a new idea, boundary averaging, to address the question: Does averaging also work well in AdS/BCFT? Talks are available for watching every day via Youtube, links are on the main page. 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: Automorphic Spectra and the Conformal Bootstrap Nov 22-26, 2021: Higher structures in geometry and physics, Chern Institute of Mathematics, Nankai University 9. Abstract: Recently, higher categorical understandings of quantum field theories have been rapidly developing. StringStringfinal . 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. Chen-Te Ma (Asia Pacific Center for Theoretical Physics) Georgios Linardopoulos (Wigner Research Centre for Physics) 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. Title: Quivers for 3-manifolds I dont think I was misrepresenting those at all. 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. Title: Approximations for Calabi-Yau and other special holonomy/structure metrics Recently, a rigorous probabilistic construction of the path integral was provided using the Gaussian Free Field. The methods can also be extended to SU(n) or G2 structure metrics This public lecture is also a lecture in the Zapytaj fizyka series here is the lecture website. Title: Homological blocks and R-matrices His third talk emphasizes thinking of space-time vectors as two by two matrices (see section 40.4 of my QM book). [Slides] [Video], Lauren Williams (Harvard University) 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). LQG calculations claim to reproduce the semi-classical limit. In our examples we find agreement with the flux modularity conjecture of Kachru, Nally, and Yang. Abstract:We discuss abelian 3d N=2 theories T[,U(1)] engineered by plumbing manifolds . We will speak about the history of Keplers conjecture. TheamplituhedronAn,k,m(Z)is the image of the positive Grassmannian Grk,n0under a positive linear mapRnRk+m.
