Entropic optimal transport is widely used in practice to compute optimal transport costs and maps. This is why the study of the convergence rates towards the unregularized problem is important. I will present how to …

We introduce a spatiotemporal self-exciting point process $(N_t(x))$, boundedly finite both over time $[0,\infty)$ and space $\mathscr X$, with excitation structure determined by a graphon $W$ on $\mathscr{X}^2$. …

Robert Koprinkov (10:15 -> 10:45) Toward Physics-Constrained Gaussian Process regression Abstract: Gaussian Process regression has often been used for the modeling of physical problems. Solutions of these …

Mikhail Ovcharenko offers an alternative definition of weighted generalised Grassmannians to that of Corti-Reid and Qureshi-Szendroi. I will go over the older definition and its difference with the alternative one, …

This talk is devoted to a probabilistic approach to the cubic nonlinear Schrödinger equation (NLS) on the two-dimensional sphere, where we study the collective behavior of random initial data supported below the …

In this talk we describe a dictionary between a family of (holomorphic) homogeneous quadratic fields in C^2 and translation surfaces defined by unfolding a triangular billiard. This dictionary translates the …

After brief recalls (of classical D-modules and derived algebraic geometry), we'll introduce different notions of D-modules in the setting of derived algebraic geometry. One natural definition is sheaves on the de …

Existence of "bimerons" by a concentration-compactness argument relying on proximity with harmonic maps, in a restricted range of parameters. To be compared with the simpler argument for "skyrmions".

Title: Slice knots and exotic R^4's Abstract: Knots are a fundamental tool to understand 3- and 4-dimensional topology. A particularly relevant class of knots, having close connection to 4-manifolds topology, …

En partenariat avec Animaths, Femmes&mathématiques, l'Institut de mathématiques de Toulouse organise les Journées Filles, Maths et Informatique.  L'objectif de cette journée est d'encourager les jeunes femmes …
