La controlabilite approchee d'une classe d'equations differentielles non lineaires avec retard fi ni.

Abstract

In this thesis, we are interested in a semi-linear ordinary differential equation with a neutral term and finite delay. The purpose of this work is to show that this equation is approximately controllable in finite time. The result is obtained by assuming that the linear part of the equation is approximately controllable. An example is given at the end of this study to illustrate its application.
