摘要
In this paper, we study the combined effect of concave and convex nonlinearities on the number of positive solutions for semilinear elliptic equations with a sign-changing weight function. With the help of the Nehari manifold, we prove that there are at least two positive solutions for Eq. (E-lambda,E-f) in bounded domains. (c) 2005 Elsevier Inc. All rights reserved.
