This paper is concerned with the study of multiple positive solutions to the following elliptic problem involving a nonhomogeneous operator with nonstandard growth of p-q type and singular nonlinearitieswhere Ω is a bounded domain inLp,qu := div(|∇u| p−2 ∇u + |∇u| q−2 ∇u), 1 < p < q < ∞, γ ∈ (0, 1), and f is a continuous nondecreasing map satisfying suitable conditions. By constructing two distinctive pairs of strict sub and super solution, and using fixed point theorems by Amann [1], we prove existence of three positive solutions in the positive cone of C δ (Ω) and in a certain range of λ.
