Positive Solutions for a Class of Quasilinear Elliptic Equations with a Dirichlet Problem

Abstract

In this paper, we study the following problem -Δ_p u = h(x)u^q + f(u), u∈W_0^{1,p}(Ω), u > 0 in Ω, where Ω is a bounded smooth domain in R^N (N ≥ 3), 0 < q < 1. By using Mountain Pass Theorem, we prove that there exists at least two positive solutions under suitable assumptions on the nonlinearity.
