Infinitely many weak solutions for a class of quasilinear elliptic systems
In this paper we deal with the existence of weak solutions for a quasilinear elliptic system. More precisely the existence of an exactly determined open interval of positive parameters for which the system admits infinitely many weak solutions is established. Our proofs are based on variational methods. (C) 2010 Elsevier Ltd. All rights reserved.
