| Abstract: | 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. |
| Keywords: | Biharmonic equation Nonlinearity concave at the origin Multiple solutions |
