Abstract
The elliptic variational inequality of the first kind for the "obstacle problem" is considered. This elliptic variational inequality is related to second order partial differential operator. The physical and mathematical interpretation and some properties of the solution are given.
1- Introduction
An important and very useful class of non-linear problems arising from mechanics, Physics etc. consists of the so-called variational inequalities. In this paper we shall restrict our attention to the study of the existence, uniqueness, and properties of the solutions of elliptic variational inequality EVI, which have two classes, namely EVI of the first kind EVI of the second kind.
