This thesis is mainly concerned with the problem of realization of homogeneous Besov and Sobolev spaces on the whole space, and some half-spaces. This problem of realization of function spaces appears naturally when studying the global well-posedness

We examine the structure of a class of Sobolev spaces. We also show that the unitization of a locally uniformly A-convex algebra is not, in general, of the same type.

On se propose dans cet article d'établir l'existence et la continuité d'un opérateur de trace de fonctions sur le bord d'un domaine $\Omega$ plan possédant la propriété de $(1,p)-$extension de Sobolev. Cet opérateur sera défini sur l'espace f

In this thesis, we study elliptic eigenvalue problems with singular potentials, motivated by several models in physics and quantum chemistry, and we propose a discontinuous Galerkin hp finite element method for their solution. In these models, singul

On considere une variete riemannienne $(M, g)$ non compacte, complete, a geometrie bornee et courbure de Ricci parallele. Nous montrons que certains operateurs “affines” en la courbure de Ricci sont localement inversibles, dans des espaces de Sob

This thesis is devoted to the mathematical analysis of heterogeneous models raised by fluid mechanics. In particular, it is devoted to the theoretical study of partial differential equations used to describe the three main models that we present belo

We study a hyperbolic version of a system of Von Karman type on a compact Kähler manifold of complex dimension m⩾2, and prove the local well-posedness of the corresponding Cauchy problem in a suitable function space frame, as well as an almost glo

We study a parabolic version of a system of Von Karman type on a compact Kähler manifold of arbitrary dimension. We provide local in time regular solutions, which can be extended to global bounded ones if the data of the problem are small.
