Abstract:
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:
We prove, in the setting of Orlicz-Sobolev spaces, the existence of
bounded solutions for some strongly nonlinear elliptic equations
with operator of the principal part having degenerate coercivity and
lower order terms not satisfying the sign condition. The data have a
suitable summability and no Δ2-condition is needed for the
considered N-functions.

Abstract:
In this paper , we study the existence of a weak solutions for the
initial-boundary value problems of the strongly nonlinear degenerated parabolic
equation,
where
A is a Leray-lions operator acted from
Lp(0,T,W01,p(Ώ,w)) into its dual. g(x,t,u,∇ u)
is a nonlinear term with critical growth condition with respect to ∇ u
and no growth with respect to u.
The source term f is assumed to belong to Lp'(0,T,W-1,p'(Ώ,w*)).
∂u
+A(u)+g(x,t,u,∇ u)=f
