A Semi Discrete Dynamical System for a 2D Dissipative Quasi Geostrophic Equation
Maithem Moalla-Trabelsi, Ezzeddine Zahrouni
A semi-discretization in time, according to a full implicit Euler scheme, for a 2D dissipative quasi geostrophic equation, is studied. We prove existence, uniqueness and regularity…

Global Existence of Solutions to the 2D subcritical dissipative Quasi-Geostrophic equation and persistency of the initial regularity
Ramzi May, Ezzeddine Zahrouni
In this paper, we prove that if the initial data and its Riesz transforms ( and ) belong to the space $(\overline{S(\mathbb{R}^2))}^{B…
