A convexity criterion via the De Giorgi slope

Tahar Z. Boulmezaoud, Aris Daniilidis, TrÃ Minh LÃª

Let $X$ be a Banach space and $f \in C^{1} (X)$ be bounded from below. We show that if for some $m \geq 1$ , the function $x \mapsto ∥\nabla f (x) ∥^{m}$ is convex, then $f$ is con…

On Navier-Stokes equations arising from the rotation of an obstacle in a fluid

Tahar ZamÃ¨ne 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…

Inverted finite elements approximation of the Neumann problem for second order elliptic equations in exterior two-dimensional domains

R Belbaki, S K Bhowmik, T Z Boulmezaoud +2

We use inverted finite elements method for approximating solutions of second order elliptic equations with non-constant coefficients varying to infinity in the exterior of a 2D bou…
