Abstract

In this paper we consider the fourth-order problem [ Delta(2)u = mu|u|(s-1)u + |u| (2{*}-2)u in Omega, [ u, -Delta u > 0 in Omega, u, Delta u = 0 on partial derivative Omega, where Omega is a smooth bounded domain in R-N, N >= 5 and 2({*}) = 2N/(N - 4). We assume 2 <= s + 1 < 2({*}) in case N >= 8 and 2({*}) - 2 < s + 1 < 2({*}) for the critical dimensions N = 5, 6, 7. Then we prove that if Omega has a rich topology, described by its Lusternik-Schnirelmann category, then the problem has multiple solutions, at least as many as cat(Omega)(Omega), in case the parameter mu > 0 is sufficiently small.
