摘要
The aim of this paper is investigating the existence of one or more critical points of a family of functionals which generalizes the model problem (J) over bar (u) = integral(Omega) (S) over bar (x. u) vertical bar del u vertical bar(p) dx - integral(Omega) G(x, u)dx in the Banach space W(0)(1,p) (Omega) boolean AND L(infinity) (Omega) a bounded domain in R(N). In order to use "classical" theorems, a suitable variant of condition ( C) is proved and W(0)(1,p) (Omega) is decomposed according to a "good" sequence of finite dimensional subspaces.
