摘要
In this work, we use variational methods to prove the existence of a positive solution for the following class of elliptic problems, -Delta u + u = u(q) + epsilon u(2)*(-1), in Omega, u > 0, in Omega, (P-epsilon) u is an element of H-0(1) (Omega), where Omega subset of R-N is an exterior domain, N >= 3, 1 < q < 2* - 1 and epsilon is a small positive parameter.
