Abstract
This paper is concerned with the study of the existence of nontrivial solutions for elliptic systems involving the
p
-Laplacian. By using the result of [B. Ricceri, A three critical points theorem revisited, Nonlinear Anal. (2008), in press (
doi:10.1016/j.na.2008.04.010)], we establish the existence of at least three solutions.
