The analogies between the iteration of holomorphic maps and the action of Kleinian groups were first systematically explored by Dennis Sullivan in the mid-1980s. In the landmark paper, where he famously proved …

Self-supervised learning (SSL) can produce highly informative representations without labeled data, yet what structure these representations capture and how training dynamics select them remain poorly understood. …

Le théorème de rigidité d'Ivanov stipule que tout automorphisme du complexe des courbes est induit par un élément du mapping class group. Dans cet exposé, j'expliquerai un résultat analogue pour le groupe de …

Logarithmic enumerative geometry is populated by a number of geometric/combinatorial constructions that appear over and over, in particular they always appear whenever talking about degenerations and gluing …

In a series of joint projects with T. Blomme, T.Blomme and A. Urundolil-Kumaran we have been introducing and studying a refined version of Gromov-Witten invariants for surfaces relative to an anticanonical divisor, …

Abstract: In two-player zero-sum games, for every ε > 0, ε-optimal strategies can be selected Lipschitz continuously as the payoffs vary. For general two-player games this fails as strongly as possible: for any ε …

The map $u_*\colon\mathbb R^3\to\mathbb S^2$, $x\mapsto x/|x|$, is a local minimizer of the Dirichlet energy $\int |\nabla u|^2$ among $\mathbb S^2$-valued maps. I will present recent results, and open questions, …
