Abstract:
A standard Min-Max procedure to find critical points for a ${C^1}$functional $\varphi$ verifying a compactness condition of Palais-Smale type on a smooth Banach manifold $X$ consists of finding an appropriate class $\mathcal {F}$ of compact subsets of $X$, all containing a fixed boundary $B$, and then showing that the value $c = {\inf _{A \in \mathcal {F}}}{\sup _{x \in A}}\varphi (x)$ is a critical level, provided it satisfies $\sup \varphi (B) < c$. In this paper, we refine this procedure by relaxing the boundary condition.References
