Resumen:
In this talk, I will present a couple of recent results on the mathematical description of some phenomena in the dynamics of 2D incompressible stably stratified fluids. We will consider internal waves as the response to small perturbations of the hydrostatic equilibrium.The inclination of their group velocity with respect to the vertical (gravity) is completely determined by their time frequency. Therefore the reflection on a sloping boundary cannot follow Descartes’ laws and gives rise to interesting phenomena. In the second part, we will also investigate the stability of a more general class of steady states (shear flows)
