This paper is concerned with the existence result of the unilateral problem associated to the equations of the type

in Orlicz spaces, without assuming the sign condition in the nonlinearity g. The source term f belongs to L¹(Ώ).

Abstract:

In this paper, we study the existence of renormalized solutions for the nonlinear parabolic problem: ,where the right side belongs to L¹(Ω×(0,T)) and b(u) is unbounded function of u, the term div(a(x,t,u,∇u)) is a Leray--Lions operator and the function φ is a nonlinear lower order and satisfy only the growth condition.
