Title: Some problems in the dynamics of stratified fluids

Speaker: Dr. Roberta Bianchini
Affiliation: Italian National Research Council, Istituto per le Applicazioni del Calcolo “Mauro Picone” (Italy)

Abstract. In this talk, I will present some recent results on the mathematical description of some phenomena in the dynamics of 2D incompressible stratified fluids, in the stably stratified regime. In the first part of the talk, we will consider small perturbations of the hydrostatic equilibrium, giving rise to internal waves. We will study the propagation of internal waves in a critical geometry. Then, we will investigate the stability of a more general class of steady states (shear flows)
