Seminari di Sistemi Dinamici Olomorfi 2018-2019

seminar: Hydrodynamic limits in hyperbolic scaling

speaker: Stefano Olla (CEREMADE, Université Paris Dauphine)

abstract: I will present a review of old and new results (and open problems) concerning scaling limits for conservation laws in the hyperbolic space-time scale, for a system of anharmonic oscillators with external boundary tension. The macroscopic equation is given by the compressible Euler system, with corresponding boundary conditions. The problem is particularly challenging when shock waves are present. Some results exists when the microscopic dynamics is perturbed by a conservative stochastic viscosity. Works in Collaboration with Stefano Marchesani (GSSI) and Lu Xu (CEREMADE).
