Abstract: | In this paper, we establish an existence theorem of two local minima for functionals on reflexive Banach space. As a consequence, we obtain an existence theorem of three critical points which improves the conclusion of a result in a recent paper of G.Bonanno concerning some remarks on a three-critical-points theorem established by B. Ricceri. |
