On Navier-Stokes equations arising from the rotation of an obstacle in a fluid
Tahar Zamène Boulmezaoud, Nabil Kerdid, Amel Kourta
We consider the modified Navier-Stokes equations in R3 describing the motion of a fluid in the presence of a rotating rigid body. Weighted Sobolev spaces are used to describe the b…

A simple formula of the magnetic potential and of the stray field energy induced by a given magnetization
Tahar Zamene Boulmezaoud
The primary aim of this paper is the derivation and the proof of a simple and tractable formula for the stray field energy in micromagnetic problems. The formula is based on an exp…
