Description
Abstract: I will talk about recent mathematical progress on asymptotic regimes for inviscid stratified fluid models, focusing on two topics that remain only partially understood: (i) the long-time dynamics and (ii) the hydrostatic limit. As a guiding example I will use the classical 2d Euler-Boussinesq system. I will try to connect these two questions for this model, highlighting the role of (in)stability issues and important mechanism such as mixing or dispersion.
