Thematic semester 2026 : Interacting particles, PDEs and applications
3 Mars
Many complex systems in physics, biology, and the social sciences consist of a large number of interacting agents whose emergent behavior can often be described by nonlinear PDEs. Over recent decades, significant progress has been made in understanding the …
"Gaston Darboux, la profondeur des surfaces" : an exhibition presented at the library from 1 Dec. 2025 to 16 Jan. 2026

Polynomialité des invariants tropicaux raffinés

Séminaire de Géométrie Complexe

Mével, Gurvan
3 September 2026, 10:30 → 11:30

Les invariants tropicaux raffinés sont des polynômes obtenus par des comptages de courbes tropicales. Ils sont liés à des énumérations de courbes sur des surfaces toriques, et satisfont certaines propriétés …

Nonstandard Large and Moderate Deviations for the Laguerre Ensemble

Séminaire de Probabilités

Götz, Helene
8 September 2026, 09:50 → 10:50

We show limit theorems for the weighted spectral measure of the Laguerre ensemble under a nonstandard scaling, when the parameter grows faster than the matrix size. For this parameter scaling, the limit behavior is …

Convergence of the Expectation Maximization algorithm revisited

Séminaire de Statistique et Optimisation

Noll, Dominikus
8 September 2026, 11:15 → 12:15
1R3, 1er étage

The EM-algorithm assures monotone increase of the incomplete data likelihood, but does not in general guarantee convergence of the parameter estimates. We take a fresh look at the situation and present novel …
