摘要
In this paper, we show that the following system: -Delta u + V(x)u = g(x, v), -Delta v + V(x)v = f(x, u), x is an element of R-N (0.1) possesses at least one non-trivial solution pair (u, v), where f(x,t), g(x, t) are continuous functions on R-N x R and asymptotically linear as t -> +infinity, and V(x) is allowed to be sign-changing.
