Least-energy solutions for the Brézis-Nirenberg problem in dimension 3 in the non-coercive case

We consider in this talk the celebrated Brézis-Nirenberg equation in the non-coercive case $\lambda > \Lambda_1$, where $\Lambda_1$ is the first eigenvalue of the Laplacian on a bounded open set of...

Topological classification of chiral and particle-hole symmetric insulators in low dimension

Motivated by the study of periodic Hamiltonians enjoying chiral or particle-hole symmetry, like the SSH model or the Kitaev chain, we present a topological study of families of symmetric functions fro...

Kinetic scheme for non linear hyperbolic and parabolic problems: application to compressible flows (Part 2)

We present kinetic type methods able to approximate compressible type flow, with or without viscous and thermal effects. Many numerical example illustrate the methods and show effectiveness. The work ...

Equivariant L-Classes for finite group actions on singular spaces.

For algebraic actions of finite groups on singular complex algebraic varieties, equivariant Hirzebruch characteristic classes have been defined by Cappell, Maxim, Schürmann and Shaneson. The correspon...

Virtual finite element and hyperbolic problems: the PAMPA algorithm

In this paper, we explore the use of the Virtual Element Method concepts to solve scalar and system hyperbolic problems on general polygonal grids. The new schemes stem from the active flux approach [...

Energy identity for a higher dimensional Sacks-Uhlenbeck approximation

In this talk, we introduce a family of functionals approximating the conformally invariant Dirichlet n-energy of maps between two Riemannian manifolds $(M^n,g)$ and $(N,h)$, which admit critical point...

Large deviations for SPDEs

This talk is about large deviations for solutions to quasilinear SPDEs with small Gaussian noise. We consider a general variational framework for SPDEs. The large deviation principle (LDP) has been su...

Emergence of kinetic state and Markovian dynamics in exactly solvable models of open quantum systems

Typically, the theory of open quantum systems studies the dynamics of the reduced state (density operator) of the system. However, in the early stages of evolution, it is impossible to separate the re...

The Cauchy problem for Boltzmann type equations

The talk will discuss a stability property for Boltzmann type equations,  including cases of quantum quasi/particles. It will focus on general, discrete velocity equations. The result implies exi...
