The ergodic problem for fractional Hamilton-Jacobi equations

In this talk, I will report some results on the solvability of the ergodic problem linked to Hamilton-Jacobi equations with fractional diffusion and power-type gradient nonlinearity, posed on a bounde...

Pattern formation in a Phenotype-Structured Shigesada–Kawasaki–Teramoto Model

In this seminar, I will present a recent modelling framework for heterogeneous populations, in which individuals’ movement and interactions depend on their phenotype. As a case study, I consider an ex...

Nonlinear exchange dynamics for spin systems

We discuss a class of nonlinear exchange dynamics for interacting spin systems, inspired by Boltzmann-type equations from kinetic theory. These dynamics provide a nonlinear Monte Carlo approach for sa...

Effective conductivity in random media

We are interested in computing the electric field generated by a neutral, localized charge distribution in a random medium, modeled by a linear elliptic equation in divergence form. First, I will pres...

An Energy Balance Model with Vertical Resolution and Horizontal Transport

Energy balance climate models provide a relatively simple framework in which some fundamental mechanisms of climate dynamics can be studied analytically. I will first recall the classical scalar model...

Correlations in a Repulsive Dilute Fermi Gas

Abstract: In recent years, dilute quantum gases have attracted considerable interest from the mathematical and experimental physics communities, partly due to advances in ultracold atomic gas experime...

Inhomogeneous Einstein metrics on complex projective spaces

The complex projective space CP^n, which parametrizes the complex lines in C^{n+1}, is one of the most extensively studied objects in algebraic and complex geometry. The first Einstein metric discover...

Semi-Lagrangian schemes for first order Mean Field Games and for Hamilton-Jacobi equations on networks

We study semi-Lagrangian schemes for the numerical approximation of first-order Mean Field Games and Hamilton–Jacobi equations on networks. As a first contribution, we present a numerical scheme for a...

Minimizing N-harmonic maps with partially constrained boundary conditions of prescribed degree

In this talk we will focus for $N\geq 2$ on fractional $W^{1-1/N,N}$ maps from an $(N−1)$-dimensional sphere into itself as traces of maps with finite energies modelled on the N-Dirichlet integral. We...

Automorphic forms in the geometry of orthogonal Shimura varieties

Orthogonal Shimura varieties arise naturally as moduli spaces in algebraic geometry, one example being the moduli space of quasi-polarized K3 surfaces. Their geometry is closely related to the theory ...

Sulla congettura di Hodge per varietà hyperkähler

Abstract: La congettura di Hodge predice l'esistenza di una profonda connessione tra la struttura di Hodge associata a una varietà liscia e proiettiva e lo studio delle sue sottovarietà. La congettura...

On the derivation of the Boltzmann-Nordheim equation for weakly interacting bosons

We investigate the behaviour of a gas of weakly interacting bosons in a box with periodic boundary conditions. Starting from a quasi-free truncation of the quantum BBGKY hierarchy and performing an ul...
