We consider a family (P ) >0 of boundary value and transmission problems, which is repre-
sented as an abstract second order di¤erential equation of elliptic type with variable operator
coe¢ cients, in the framework of ...
This thesis is devoted essentially to study, in two frameworks, the existence, uniqueness
and maximal regularity of the solutions of a family of transmission problems governed by an
abstract second order di¤erential ...
This work is devoted to the study of a second order abstract di¤erential equation of
elliptic type :
u00 (x) + 2Bu0 (x) + Au (x) = f (x) ; x 2 (0; 1)
with the nonlocal boundary conditions
u (0) = u0
u (1) + Hu0 (0) ...
This thesis is on the topic of Nevanlinna theory, a powerful tool from complex analysis. In this thesis, we begin by studying how Nevanlinna Theory is derived, and continue by showing how its results and methods can be ...

This work emphasizes on the generalization to two dimensions of a new approach of function decomposition based on a
semi-classical quantification namely Semi-Classical Signal Analysis. The SCSA approach consists in ...
About the year thirty, an inequality called Hardy’s inequality was proved [See {45}, {48} ] :

In this thesis, we are concerned with integrals and derivaitves of arbitrary order.We begin
by studing a boundary value problem of fractional order derivaitve in the sens of Caputo
such that its initiale conditions contain ...
The theory of fractional di¤erential equations plays an important role in the modeling
of many processes physical, technological and biological. In recent years, a great attention
has been focused on the study of the ...
