Abstract

We study the existence of sign changing solutions to the slightly subcritical problem −u = |u|p−1−εu in , u = 0 on ∂, where is a smooth bounded domain in RN , N ≥ 3, p = (N + 2)/(N − 2) and ε > 0. We prove that, for ε small enough, there exist N pairs of solutions which change sign exactly once. Moreover, the nodal surface of these solutions intersects the boundary of , provided some suitable conditions are satisfied.
