Abstract. The existence of a positive solution for a class of asymptotically linear problems in exterior domains is established via a linking argument on the Nehari manifold and by means of a barycenter function.

“…Subsequently, taking advantages of some techniques introduced in [7], an extended study of radially symmetric problems on R N was done in [12]. Finally we wish to mention [13] where a first order Hamiltonian system with an asymptotically linear part is studied.…”
Section: ) Condition (F4) Holds If F (S)s −1 Is a Non-decreasing Funmentioning
Abstract. In this paper we establish the existence of a positive solution for an asymptotically linear elliptic problem on R N . The main difficulties to overcome are the lack of a priori bounds for PalaisSmale sequences and a lack of compactness as the domain is unbounded. For the first one we make use of techniques introduced by Lions in his work on concentration compactness. For the second we show how the fact that the "Problem at infinity" is autonomous, in contrast to just periodic, can be used in order to regain compactness.Mathematics Subject Classification. 35J60, 58E05.

This paper deals with the problem of finding positive solutions to the equation −Δu = g(x, u) on a bounded domain Ω, with Dirichlet boundary conditions. The function g can change sign and has asymptotically linear behaviour. The solutions are found using the Mountain Pass Theorem.2000 Mathematics Subject Classification: 35J20, 35J65.
