Anti-Iitaka conjecture in positive characteristic

Anti-Iitaka conjecture in positive characteristic

Marta Benozzo

A guiding problem in algebraic geometry is the classification of varieties. In dimension 1, the main invariant for their classification is the genus. Similarly, in [...]

Pierre LAZAG

04/04/2025    
11h00 - 12h00
Les mesures de Schur sont des mesures de probabilités sur les diagrammes de Young dépendant de deux ensembles dénombrables de paramètres. Introduites par Okounkov en [...]

An Introduction to Physics of Chaos

Simon Rouvet

Abstract : I will present you some general features of Physics of Chaos for a broad audience : What is it ? Where does it [...]
L’approximation equisingulière des germes analytiques

L’approximation equisingulière des germes analytiques

Aftab Yusuf PATEL

Dans cet exposé on va considérer le problème de l’approximation des germes d'espaces analytiques (réels ou complexes) de manière equisingulière. On commencera par définir ce [...]

Lambda Fleming-Viot processes arising in Bienaymé-Galton-Watson processes with logistic competition

Raphaël FORIEN

Lambda Fleming-Viot processes and Lambda coalescents were introduced in the early 2000's as a generalisation of the Fleming-Viot process and the Kingman coalescent, respectively. Such [...]

Spectral properties of the fractional Anderson model: conjectures, localization and local eigenvalue statistics

Constanza Rojas-Molina

01/04/2025    
11h00 - 12h00
We review recent results on the spectral and dynamical properties of the fractional Anderson model, part of a research program on non-local Hamiltonians with diagonal [...]

Étude statistique du facteur premier médian des entiers : lois locales, valeur moyenne, loi de répartition

Jonathan Rotgé

Dans un travail récent, McNew, Pollack et Singha Roy publient plusieurs résultats relatifs à la distribution du facteur premier médian des entiers lorsque ce dernier [...]

Combinatorial proofs for classical and intuitionistic logic [Lirica]

Lutz Straßburger

(Séminaire de l’équipe Lirica au LIS) Combinatorial proofs, or “proofs without syntax”, form a graphical semantics of proof in various logics that is canonical yet [...]

Sur un théorème d'Eisenstein

Guillaume Rond

Je parlerai du dernier article de Gotthold Eisenstein, Über eine allgemeine Eigenschaft der Reihen-Entwicklungen aller algebraischen Funktionen, paru en 1852 aux Verhandlungen de l'académie royale [...]

Eckmann-Hilton argument, from monoids to homotopy theory

Tommy Klein

Abstract : I'll be first and foremost introducing the Eckmann-Hilton argument in its most basic and algebraic form, which you may or may not be [...]

Monotone weak distributive laws in categories of algebras [LSC]

Quentin Aristote

Within the study of the semantics of programming languages, computational effects may be modelled with monads, and weak distributive laws between monads are then a [...]

Hodge structures on conformal blocks

Pierre Godfard

27/03/2025    
11h00 - 12h00
Modular functors are families of finite-dimensional representations of Mapping Class Groups of surfaces, with strong compatibility conditions. As Mapping Class Groups of surfaces are isomorphic [...]

W-algebras, Gaussian Free Fields and Selberg integrals arising from the Mukhin-Varchenko conjecture

Baptiste CERCLÉ

Two-dimensional Conformal Field Theory (CFT) is a research topic that has attracted a lot of attention in both the physics and mathematics community since its [...]

Distribution of cubic character sums

Kunjakanan Nath

In this talk, we will discuss the distribution of large cubic character sums and highlight a structure result of cubic characters with large character sums. [...]

The E-base of finite semidistributive closure lattices [LSC]

Simon Vilmin

A (finite) closure space is a pair consisting of a (finite) ground set X and a closure operator on X. When ordered by inclusion, the [...]

Lorenzo Fantini

20/03/2025    
11h00 - 12h00
