In this paper, we are concerned with the following eigenvalue problem: {-Δ_pu = λf(x, u) in Ω, u = 0 on ∂Ω, here Ω ⊂ ℝⁿ (n ≥ 2) is a C^1,α - domain and - Δ_p is the degenerate p-Laplace operator with p > 1. An interesting special case is when f = φ(x)\u\^q1-1u-ψ(x)\u\^q2-1u, 0 < q1 < q2. By using the sub- and supersolutions method and the variational method, we prove the existence of the solution of the problem under certain growth conditions for f(x, u). In the above special case, our results give the existence of at least one positive solution for q2 > p* - 1, where p* is the critical Sobolev exponent, and the existence of at least two positive and two negative solutions for q1 < p - 1 < q2 < p* - 1. We also present a 1D example which has many positive solutions for certain interval of λ and for a special value of λ it has even infinitely many solutions.
