Martedì 11 Marzo 2025, alle ore 15 precise, presso la sala conferenze
dell'IMATI di Pavia,

Luca Franzoi (Università di Milano)

terrà un seminario dal titolo:

Large amplitude quasi-periodic waves in rotating fluids.

Abstract.
The β-plane equation is a 2D approximation model of the 3D Euler-Coriolis
equations for rotating fluid. In this talk, I will start with an overview
on these equations and related problems. The goal, then, is to present a
recent result that studies the dynamics of the β-plane equation under the
effect of a highly oscillating forcing term of substantial large size,
therefore not perturbative. Moreover, we will assume the external forcing
term to be a traveling quasi-periodic wave in order to resolve a natural
and important degeneracy that arises from the rotation of the fluid. After
the statement of the main theorem, I will give the main ideas for the
construction of such solutions.
This is a joint work with Roberta Bianchini, Riccardo Montalto and Shulamit
Terracina.
