In this paper, we study the following p-Laplacian problem
−Δpu + V(x)|u|p−2u = |u|p*−2u + α(x)|u|q−2u, x ∈ RN,
u ∈ W1,p(RN),
where Δp := div(|∇u|p−2∇u) is the p-Laplacian operator, V is a nonnegative function, N > p2, 1 < p < q < p* and p* = Np/N−p is the Sobolev critical exponent. Under appropriate assumptions on V and a, we prove that this problem has at least two distinct bound state solutions.
