The multiple results of positive solutions for the following quasilinear elliptic equation: in Ω , u = 0 on ∂ Ω , are established. Here, 0 ∈ Ω is a bounded smooth domain in ℝ N , Δ p denotes the p ‐Laplacian operator, 1 ≤ q < p < N , p ∗ = N p /( N − p ), λ is a positive real parameter, and f , g are continuous functions on which are somewhere positive but which may change sign on Ω . The study is based on the extraction of Palais‐Smale sequences in the Nehari manifold.
