Abstract: Let F be a p-adic field. We consider representations of Arthur type of a classical group G over F. By use of the Endoscopic Classification, Moeglin gave an explicit way to construct Arthur packets when G is a symplectic
Abstract : The Gibbs measure problem consists in constructing a unique global invariant flow supported by the measure itself. We address this problem for the cubic nonlinear Schrödinger equation posed on the two-dimensional sphere \(\mathbb{S}^2\). In this setting, concentration phenomena
L'assimilation de données vise à combiner de manière optimale les modèles dynamiques des systèmes physiques avec les mesures disponibles afin d'estimer l'état ou les paramètres du système. Dans de nombreuses applications, l'état ou l'espace d'observation est constitué de données de
Multivariate Encryptions with LL’ perturbations Résumé: A new interesting multivariate encryption scheme. Few multivariate encryption schemes currently exist, while there exist many more multivariate signature schemes. Our algorithms will combine several ideas, in particular the idea of the LL’ perturbation originally introduced,
Résumé : Dans cet exposé, nous donnerons un point de vue d'ensemble de la théorie des algèbres centrales simples et du groupe de Brauer d'un corps. L'exposé sera guidé par l'étude des quaternions et l'étude d'exemples issus de la théorie
Abstract: In 1974, Honda proved the p-curvature conjecture for order one differential equations with rational coefficients over a number field. He demonstrated that in this setting, the p-curvature conjecture was equivalent to a theorem due to Kronecker, providing a local-global
Abstract: The talk will introduce the F-conjecture, which states that the Mori cone of the moduli space of genus g stable curves ‾Mg,n is generated by 1-dimensional strata. We will see that the question can be formulated on any Hassett space and
Résumé : En 2017, Chris Fraser a découvert une action du groupe de tresses affine étendu à d brins sur la (grosse cellule de la) grassmannienne des sous-espaces de dimension k d’un espace de dimension n, munie de sa structure
Abstract: The binormal flow, which models the evolution of vortex filaments, and the cubic nonlinear Schrödinger equation are deeply connected through the Hasimoto transform, linking vortex filament dynamics with dispersive partial differential equations. In this talk, I will give an
Danil Gubarevich soutient sa thèse, intitulée "On Gromov-Witten invariants and the Hall induction" encadrée par Dimitri Zvonkine, le jeudi 21 mai, 13h30, bâtiment Fermat, salle 2201. Résumé : The first two chapters of the manuscript provide the motivation for
