THREE SOLUTIONS FOR A CLASS OF QUASILINEAR DIRICHLET ELLIPTIC SYSTEMS INVOLVING (P,Q)-LAPLACIAN OPERATOR

We investigate the existence of three distinct solutions for a class of quasilinear Dirichlet elliptic systems involving the (p,q)-Laplacian operator. Our main tool is a recent three critical points Theorem of B. Ricceri [On a three critical points theorem, Arch. Math (Basel) 75 (2000) 220-226.
