摘要

In this paper, we study the following problem {-Δpu+V(x)|u|p-2u=K(x)f(u)+h(x) in□ N, u∈W1,p(□ N), u>0 in □ N, (*) where 1<p<N,the potential V(x) is a positive bounded function, h∈Lp'(□ N), 1/p'+1/p=1, 1<p<N, h≥0, h≠0f(s) is nonlinearity asymptotical to sp-1at infinity, that is, f(s)~O(sp-1) as s→+∞. The aim of this paper is to discuss how to use the Mountain Pass theorem to show the existence of positive solutions of the present problem. Under appropriate assumptions on V, K, h and f, we prove that problem (*) has at least two positive solutions even if the nonlinearity f(s) does not satisfy the Ambrosetti-Rabinowitz type condition: 0≤F(u)≤∫uo f(s)ds≤1/p+θ f(u)u, u>0, θ>0.
