【 摘 要 】

In this paper, we investigate the existence of multiple solutions for a class of biharmonic equations where the nonlinearity involves a concave term at the origin. The solutions are obtained from the versions of mountain pass lemma and linking theorem. (C) 2011 Elsevier Inc. All rights reserved.
