摘要
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) vertical bar u vertical bar(9-2)u in Omega with 1 < q < p < an > 0, under the Dirichlet boundary condition, where Omega is a bounded domain in R-N and m(q) is a weight function in L-infinity (Omega) admitting sign-change.
