摘要
In this article, we consider the existence of multiple solutions to the elliptic problem -Delta u = lambda u(q) + u(s) + mu u(P) in Omega, u > 0 in Omega, u = 0 on partial derivative Omega, where Omega subset of R-N (N >= 3) is a bounded domain with smooth boundary Omega partial derivative, o <q < 1 < s < 2* - 1 <= p, 2* := 2N/N-2 lambda and mu are nonnegative parameters. By using variational methods, truncation and Moser iteration techniques, we show that if the parameters A and p are small enough, then the problem has at least two positive solutions.
