摘要:

The main purpose of this paper is to establish the existence of multiple so-lutions for singular elliptic system involving the critical Sobolev-Hardy exponents and concave-convex nonlinearities. It is shown, by means of variational methods, that under certain conditions, the system has at least two positive solutions.

关键词: singular elliptic system, concave-convex nonlinearities, positive solution, Ne-hari manifold, critical Sobolev-Hardy exponent
