Symmetry breaking for semilinear elliptic problems in higher dimensions

In this talk, we present an existence result for semilinear elliptic problems of the form -Delta u + u = f(u), u > 0, u in H^1_0(A), where A denotes either an annulus or the exterior of a ball in R...

The limiting case of the fractional Caffarelli-Kohn-Nirenberg inequality in dimension one

Abstract: We study the limiting case $\gamma\to(1/2)^-$ in dimension one for the fractional Caffarelli-Kohn-Nirenberg inequality, obtaining Onofri's inequality in the unit disk as a limit. An importan...

On the Brezis-Nirenberg problem in low dimensions

In this talk I will present some recent results regarding some open problem for a classical critical problem in a bounded domain in low dimensions. We will discuss the question of the existence of pos...

Degenerate deterministic Mean Field Games

I will talk about a research project with Y. Achdou, A. Cutri', C. Marchi and N. Tchou about some models of degenerate deterministic Mean Field Games (MFG). These games are modelized by a system of tw...

Chiralization of cluster varieties

The chiralization in the title denotes a certain procedure which turns cluster X-varieties into q-W algebras. Many important notions from cluster and q-W worlds, such as mutations, global functions, s...

Asymptotics for solubility of unit equations over real quadratic fields

For a real quadratic field K and positive integer r, we prove an asymptotic formula for the number of rational integers of bounded absolute value that can be written as a sum of r units of the ring of...

The Gamma disordered Aztec diamond

The Aztec diamond, under the uniform measure on domino tilings, is one of the classic examples of an exactly solvable model in probability and statistical mechanics. Its rich geometric features—such a...
