摘要
In this paper, we study the existence and multiplicity of positive solutions for the Dirichlet problem -Delta u =lambda f(z) |u|(q-2) u + g(z) |u|(2*- 2) u in Omega, where lambda > 0, 1 <= q < 2, 2* = 2N/( N - 2), 0 is an element of Omega subset of R-N (N >= 3) is a bounded domain with smooth boundary partial derivative Omega, and f, g are nonnegative continuous functions on <(Omega)over bar>.
