摘要
In this paper we investigate the existence of positive ground state solution for the following class of elliptic equations -Delta u + V(x)u = K (x) f (u) in R-N, where N >= 3, V, K are nonnegative continuous functions and f is a continuous function with a quasicritical growth. Here, we prove a Hardy-type inequality and use it together with variational method to get a ground state solution. (C) 2012 Elsevier Inc. All rights reserved.
