Improved convergence rates and larger initial data for the 3D-2D asymptotics of the rotating magnetohydrodynamicand rotating fluids systems
Frédéric Charve
We recently proved that if their initial velocity and magnetic field both are the sum of a classical 3D-part and some 2D-part (i.-e. depending only on the horizontal space variable…

Convergence rates for a rotating MHD system with evanescent viscosity
Frédéric Charve, Zhuoya Yao
In this article, we focus on a MHD model that takes into account the Coriolis force. In this case, the strength of the rotation is measured by the Rossby number (positive). Un…

Mixed 3D-2D asymptotics for the weak and strong solutions of the rotating magnetohydrodynamic system
Frédéric Charve, Van-Sang Ngo
In this article, we consider the 3D-rotating magnetohydrodynamic (MHD) system when the initial velocity and magnetic field both feature some 2D-part (i.-e. depending only on the ho…
