Abstract
In this paper, we deal with the existence of a sign-changing solution and the uniqueness of a positive solution for quasilinear elliptic equations of the form -mu Delta_p u-Delta_q u=lambda m_q(x)|u|^{q-2}u in Omega with 1<q<p<infty and mu>0, under the Dirichlet boundary condition, where Omega is a bounded domain in R^N and m_q is a weight function in L^{infty}(Omega) admitting sign-change.
