10.5446/53517 (DOI) | So I'd like to start by thanking the organizers for giving me the opportunity to talk about my work at this virtual conference. And I'd like to mention that part of the work that I'm talking about today is joined with Dennis Ossin, Carolyn Abbott, and some ongoing work with Alex Rasmussen. So in the area of geometric ... | The study of the poset of hyperbolic structures H(G) on a group G was initiated by Abbott-Balasubramanya-Osin. However, the sub-poset of quasi- parabolic structures is still very far from being understood and several questions remain unanswered. In this talk, I will talk about the motivation behind our work, describe s... |
10.5446/53520 (DOI) | So welcome everybody to this talk on action of the criminal group on the cut zero cube complex. Before starting, I would like to thank the organizer of the virtual geometry group theory conference to have invited me to give this talk. And I would like also to thank Guillemin and Fett for the technical help support. So... | The Cremona group is the group of birational transformations of the projective plane.

10.5446/53522 (DOI) | So thank you very much to the organisers for organising this very nice virtual conference and for the opportunity to speak. So I'm going to be talking about quasi-actions and almost normal subgroups. So to motivate the talk I'm going to be talking about how quasi-actions arise quite naturally in various problems in ge... | If a group G acts isometrically on a metric space X and Y is any metric space that is quasi-isometric to X, then G quasi-acts on Y. A fundamental problem in geometric group theory is to straighten (or quasi-conjugate) a quasi-action to an isometric action on a nice space. We will introduce and investigate discretisable... |
10.5446/53523 (DOI) | So, hello everyone. So, first of all, let me begin by thanking the organizers for inviting me to speak in this very nice virtual conference. So, as the title says today, I would like to speak about this idea of spaces of cubulations. So, what we would like to do is, well, we're going to have some cubulated group G, an... | The theory of group actions on CAT(0) cube complexes has exerted a strong influence on geometric group theory and low-dimensional topology in the last two decades. Indeed, knowing that a group G acts properly and cocompactly on a CAT(0) cube complex reveals a lot of its algebraic structure. However, in general, "cubula... |

So here's the outline. First I will give a brief introduction on the Levy-Folker-Plunk equation, and then I will introduce our numerical methods a... | We develop a numerical method for the Levy-Fokker-Planckequation with the fractional diffusive scaling. There are two main challenges. One comes from a two-fold nonlocality, that is, the need to apply the frac-tional Laplacian operator to a power law decay distribution. The other comes from long-time/small mean-free-pa... |
10.5446/53476 (DOI) | It's a pleasure to give this talk because much of the talk has been done in Shanghai in collaboration with Ming Tang there and other people who are visiting the Institute of Xi Jinping. So it's a great pleasure to see a program which has been running for several years and which is dedicated to understand how bacteria ... | At the individual scale, bacteria as E. colimove by perform-ing so-called run-and-tumble movements. This means that they alternate ajump (run phase) followed by fast re-organization phase (tumble) in whichthey decide of a new direction for run. For this reason, the population is described by a kinetic-Botlzmann equatio... |

10.5446/53479 (DOI) | So thanks a lot for the invitation. I would have very much liked to be at CIRM, you know, like everybody else here, but we'll have to do and there is hope that we will be able to meet in person again in the future. And I guess all of us have realized what we're missing. So let me talk about a new thing that I've been ... | The dynamical low-rank approximation is a low-rank factorization updating technique. It leads to differential equations for factors ina decomposition of the solution, which need to be solved numerically. The dynamical low-rank method seems particularly suitable for solving kinetic equations, because in many relevant ca... |
10.5446/53482 (DOI) | Thank you very much. Thank you for the introduction. I would like to thank the organizer for setting up this meeting and even if it's virtual, it's a real pleasure to see lots of friends at least on video. Okay, so I'm going to try to make a rather superficial review of several little models. So let me go to the list ... | This lecture is devoted to the characterization of convergence rates in some simple equations with mean field nonlinear couplings, like the Keller-Segel and Nernst-Planck systems, Cucker-Smale type models, and the Vlasov-Poisson-Fokker-Planck equation. The key point is the use of Lyapunov functionals adapted to the non... |
10.5446/53484 (DOI) | I should start mentioning that the work I'm going to report today is in two pieces with different co-authors. The first piece is with Amid Anaf, Beatrice Signorello and Tobias Werner, and then the second part with Jean-Dorbault and Christian Schmeisser. Here is a short outline of my talk. Somehow, as a long and very s... | We are concerned with deriving sharp exponential decayestimates (i.e. with maximum rate and minimum multiplicative constant )for linear, hypocoercive evolution equations. Using a modal decomposition ofthe model allows to assemble a Lyapunov functional using Lyapunov matrixinequalities for each Fourier mode.We shall ill... |
10.5446/53486 (DOI) | Thank you very much. So thanks to the organizers, thanks to Xi and Mihai for organizing this beautiful conference. I'm very sorry that I cannot be in Marseille, but anyway, so it's already very nice to have a conference like this when you're locked down in Paris, even though locked down in a week since. All right, so ... | Whether there is global regularity or finite time blow-up forthe space homogeneous Landau equation with Coulomb potential is a longstanding open problem in the mathematical analysis of kinetic models. Thistalk shows that the Hausdorff dimension of the set of singular times of theglobal weak solutions obtained by Villan... |
10.5446/53489 (DOI) | It's a pleasure to present here, unfortunately, in our virtual. I hope everything worked out. So what I'm going to talk about is joint work with my now postdoc, Stefan Gaster, with Stilian Aachen, and former postdoc of mine, who is now in Tsinghua University. And some references in the end, but if there are any furthe... | We are interested in the stabilisation of linear kinetic equations for applications in e.g. closed-loop feedback control. Progress has beenmade in recent years on stabilisation of hyperbolic balance equations usingspecial Lyapunov functions. However, those are not necessarily suitable forthe kinetic equation. We presen... |
10.5446/53490 (DOI) | Thank you very much, Mihai. So I would like to thank all the organizers and more especially Mihai for the invitation. It's a pleasure to present these two works.

10.5446/53491 (DOI) | As the final speaker, it's my duty to thank the organizers, not of whom happen to be in the room right now, so if they do show up, we'll thank them later. So we'll start slowly. We want to construct an R matrix, and we saw in Eva's talk what an R matrix was. Let me just recall this. I'll start with a single vector spa... | We explain how to use a Virasoro algebra to construct a solution to the Yang- Baxter equation acting in the tensor square of the cohomology of the Hilbert scheme of points on a general surface S. In the special case where the surface Sis C2, the construction appears in work of Maulik and Okounkov on the quantum cohomol... |
10.5446/53494 (DOI) | So today I want to explain some big picture explaining physics of the Langmuir reality. So the goal is by understanding these physics, you get sort of new context. And in fact, sort of the main bulk of the work is to actually set up not just translation but actually translator so that you can use that translator in ot... | It is believed that certain physical duality underlies various versions of Langlands duality in its geometric in carnation. By setting up a mathematical model for relevant physical theories, we suggest a program that enriches mathematical subjects such as geometric Langlands theory and symplectic duality.

Joint work with Rapha ̈el Rouquier. |
10.5446/53501 (DOI) | So, I want to talk about these fusion rings of the Linde Algebus. So, in a talk today, they will come from quantum groups, so certain tensor categories from UQG. This is mainly going back to a construction of Anderson, any more Anderson, by taking the golden group of this. But you can also get it from very different a... | In this talk I will give a short overview about fusion rings arising from quantum groups at odd and even roots of unities. These are Grothendieck rings of certain semi simple tensor categories. Then I will study these rings in more detail. The main focus of the talk will be an expectation by Cherednik that there is a c... |
10.5446/53503 (DOI) | And please tell me if I get too low on the blackboard that the people in the back don't see anything anymore. And as well as the title of the talk says, it's about T structures. T structures have been very useful in geometry, in representation theory, and other fields. And traditionally, they were mostly used in categ... | T-structures on derived categories of coherents heaves are an important tool to encode both representation-theoretic and geometric information. Unfortunately there are only a limited amount of tools available for the constructions of sucht-structures. We show how certain geometric/categorical quantum affine algebra act... |
10.5446/53504 (DOI) | Okay. So I want to thank the organizers for the invitation to speak. It's a pleasure to be here. I'm going to describe a construction that gives a partial compactification of something called the universal centralizer. And this is an example of a Coulomb branch, so it will fit into the theme of the morning talks. And ... | Let G be a semi simple algebraic group of adjoint type. The universa lcentralizer is the family of centralizers in G of regular elements in Lie (G), parametrized by their conjugacy classes. It has a natural symplectic structure, obtained by Hamiltonian reduction from the cotangent bundle T∗G. We consider a partial comp... |

10.5446/53506 (DOI) | OK. So my talk will begin with a sort of maybe a little bit introductory, maybe, to hear your acoustic. So let's begin with D, a representative, V representation. And I'll also make use of a character of my group, chi, V to C star. So associated to this data, we have two spaces, the Higgs branch. So the Higgs branch i... | Given a representation of a reductive group, Braverman-Finkelberg-Nakajima have defined a remarkable Poisson variety called the Coulomb branch.

So I want to talk about some paper with Jörn Ganev and David Jordan about what happens to this 4G theory that Sam talked about and David talked about at a Rubyview News scene. And let me be a little bit more precise what I mean by that. So David mentioned the skein algebras. So let's say sigma is a closed surf... | Character varieties of closed surfaces have a natural Poisson structure whose quantization maybe constructed in terms of the corresponding quantum group. When the quantum parameter is a root of unity, this quantization carries a central subalgebra isomorphic to the algebra of functions on the classical character variet... |
10.5446/53509 (DOI) | So my talk is going to be kind of dual in some sense to Joel's talk, so it's also going to be about the question of how to understand the representation theory of Coulomb branches. But it's going to be dual in the sense of it's going to be looking for more things like projectives rather than things like symbols. So le... | The algebra U (gln) contains a famous and beautiful commutative subalgebra, called the Gelfand-Tsetlin subalgebra. One problem which has attracted great attention over the recent decades is to classify the simple modules on which this subalgebra acts locally finitely (the Gelfand-Tsetlin modules). Ininvestigating this ... |

The first time I met Luc was in 2017. We happened to be visiting Chicago at the same time. He was there for a longer period. I was there just for a day or so for a s... | The Grothendieck–Serre conjecture predicts that every generically trivial torsor under a reductive group scheme G over a regular local ring R is trivial. We settle it in the case when G is quasi-split and R is unramified. To overcome obstacles that have so far kept the mixed characteristic case out of reach, we adapt A... |
