Entropy solutions for some nonlinear elliptic unilateral problems in anisotropic Sobolev spaces

الملخص EN

In this paper, we consider the following nonlinear elliptic unilateral equations of the type In the anisotropic Sobolev space, we prove the existence of entropy solutions for our unilateral problem, the function is a nonlinear lower order term with natural growth with respect to , satisfying the sign condition and the datum f belongs to
