52:43 Fabio Toninelli: A second growth model in the Anisotropic KPZ class Abstract: Dimer models provide natural models of (2+1)-dimensional random discrete interfaces and of stochastic interface dynamics. I will discuss two examples of such dynamics, a reversible one an...
1:02:58 Camillo De Lellis: The Onsager Theorem Abstract: In the fifties John Nash astonished the geometers with his celebrated isometric embedding theorems. A folkloristic explanation of his first theorem is that you should be able to put any p...
1:03:16 Josef Málek: On the analysis of a class of thermodynamically compatible viscoelastic... Abstract: We first summarize the derivation of viscoelastic (rate-type) fluids with stress diffusion that generates the models that are compatible with the second law of thermodynamics and where no...
28:16 Evelyne Miot: An asymptotic regime for the Vlasov-Poisson system Abstract: We investigate the gyrokinetic limit for the two-dimensional Vlasov-Poisson system in a regime studied by F. Golse and L. Saint-Raymond. First we establish the convergence towards the Eul...
1:01:59 Toshiaki Hishida : Lq-Lr estimates of a generalized Oseen evolution operator... Abstract: Consider the motion of a viscous incompressible fluid in a 3D exterior domain D when a rigid body ℝ3∖D moves with prescribed time-dependent translational and angular velocities. For the l...
49:52 Ping Zhang: Large time behavior os solutions to 3-D MHD system with initial data near equilibrium Abstract: Given initial data (b0,u0) close enough to the equilibrium state (e3,0), we prove that the 3-D incompressible MHD system without magnetic diffusion has a unique global solution (b,u). Mor...
1:48:42 Gilles Dowek : Informatique et physique : quelques interactions Recording during the thematic meeting : "Algorithm and Programming" the May 2, 2017 at the Centre International de Rencontres Mathématiques (Marseille, France)
Filmmaker: Guillaume Hennenfent

1:57:32 Gérard Berry : L’importance des langages en informatique Recording during the thematic meeting : "Algorithm and Programming" the May 2, 2017 at the Centre International de Rencontres Mathématiques (Marseille, France)
Filmmaker: Guillaume Hennenfent
Fin...
2:30:40 Sylvie Boldo : Arithmétique à virgule flottante : plaie ou terrain de jeu ? Résumé : Nous confions à nos ordinateurs de nombreux calculs mais la machine a des limites due à son arithmétique dite à virgule flottante. D'une part chaque calcul est effectué avec un certain no...
1:13:29 Gilles Dowek : La difficile explication des résultats des calculs : des preuves automatiques à ... Recording during the thematic meeting : "Algorithm and Programming" the May 2, 2017 at the Centre International de Rencontres Mathématiques (Marseille, France)

1:29:26 Gérard Berry : L'informatique, de la révolution technique à la révolution mentale Recording during the thematic meeting : "Algorithm and Programming" the May 2, 2017 at the Centre International de Rencontres Mathématiques (Marseille, France)
Filmmaker: Guillaume Hennenfent
Fin...
54:31 Martin Hairer: Weak universality of the KPZ equation with arbitrary nonlinearities Recording during the thematic meeting: "Qualitative Methods in KPZ Universality" the April 27, 2017 at the Centre International de Rencontres Mathématiques (Marseille, France)
Filmmaker: Guillaume...
44:50 Jinho Baik: Multi-time distribution of periodic TASEP​ Abstract: We consider periodic TASEP with periodic step initial condition, and evaluate the joint distribution of the locations of m particles. For arbitrary indices and times, we find a formula fo...
46:15 Dmitry Ioffe: Low temperature interfaces and level lines in the critical prewetting regime Abstract: Complete wetting in the context of the low temperature two-dimensional Ising model is characterized by creation of a mesoscopic size layer of the "-" phase above an active substrate. Addi...
50:12 Vadim Gorin: Tilings and non-intersecting paths beyond integrable cases Abstract: The talk is about a class of systems of 2d statistical mechanics, such as random tilings, noncolliding walks, log-gases and random matrix-type distributions. Specific members in this clas...
1:26:10 Tom Bridgeland: Wall-crossing for Donaldson-Thomas invariants Abstract: There is a very general story, due to Joyce and Kontsevich-Soibelman, which associates to a CY3 (three-dimensional Calabi-Yau) triangulated category equipped with a stability condition so...
59:44 Jean-Baptiste Teyssier: Skeletons and moduli of Stokes torsors Abstract: In the local classification of differential equations of one complex variable, torsors under a certain sheaf of algebraic groups (the Stokes sheaf) play a central role. On the other hand,...
1:04:28 Javier Fresán: Exponential motives Abstract: I will sketch the construction - following ideas of Kontsevich and Nori - of a Tannakian category of exponential motives over a subfield of the complex numbers. It is a universal cohomolo...
1:25:18 Andrea D'Agnolo : On the Riemann-Hilbert correspondence for irregular holonomic D-modules Abstract: The classical Riemann-Hilbert correspondence establishes an equivalence between the triangulated categories of regular holonomic D-modules and of constructible sheaves. In a joint work wi...
1:02:53 Dmytro Shklyarov: Semi-infinite Hodge structures in noncommutative geometry Abstract: Homological mirror symmetry asserts that the connection, discovered by physicists, between a count of rational curves in a Calabi-Yau manifold and period integrals of its mirror should fo...
