Résumé Dans ce travail, nous étudions la croissance et la distribution des zéro des solutions des équations di¤érentielles linéaires dans le disque unité.La première partie consiste à étudier l exposant de convergence ...

This thesis is concerned with new results of the waves diffraction by a strictly convex obstacle. Our objective is to produce the high frequency asymptotic expansion of the Helmholtz equation solution providing a boundary ...

Résumé Le présent manuscrit traite de deux grands volets de l analyse fonctionnelle. Le premier concerne les extensions de certaines classes d opérateurs symétriques, nottament les opérateurs de Caleman. Les méthode ...

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 ...

About the year thirty, an inequality called Hardy’s inequality was proved [See {45}, {48} ] : for and an arbitrary measurable positive function we have . (IH) with condition . is an optimal constant (the less possible). If ...

In the Big Data Era, the management of energy consumption by servers and data centers has become a challenging issue for companies, institutions, and countries. In data-centric applications, Database Management Systems ...
