The multiparameter random simplicial complexes are generalizations of the Erdős–Rényi random graphs that allow higher-dimensional interactions. They also have rich topological structure. In this talk we …

Cet exposé se veut une introduction à l'une des frontières actuelles de l'étude de la stabilité non linéaire des ondes progressives des équations aux dérivées partielles. Spécifiquement on y discute comment la …

The goal of this talk is to give an introductory account of a new class of non-semisimple topological field theories in three dimensions. These theories are defined using the quantum representation theory of a Lie …

The continuity equation models the movement of d-dimensional particles following a vector field $v_t(x)$. Many natural phenomena can be described in this setting, like the meteorological ones. In this talk, we are …

Let F_n be the free group on n generators and H be its first rational homology group. The "bivariant" coefficients of the title are the representations of Aut(F_n) given by arbitrary tensor products of H and its …

Consider the following problem: for S a subset of Z^2, we want  to count the plane lattice walks with steps in S, that start from (0,0)  and always remain in the first quadrant. This enumerative …

La journée Statistique et Sporta pour but de rassembler la communauté toulousaine intéressée par l’interaction entre statistique et sport. De l’optimisation de la performance individuelle à la prévention des …

Given a basis for a linear subspace U of nxn matrices, we study the problem of either producing a rank-one matrix in U, or else certifying that none exist. While this problem is NP-Hard in the worst case, we present …

Sparse interpolation is the task of learning the sparse representation of a polynomial, given a way to evaluate it at chosen points. Compared to standard (dense) interpolation, the goal is to use a number of …
