In the development to a nonsmooth setting of some M. Schechter results [M. Schechter
, Topol. Methods Nonlinear Anal. 6, No. 2, 295-308 (1995; Zbl 0864.58007
)] the author shows for continuous functionals on metric spaces, how quantitative deformation properties can be used to obtain saddle-point type results, even for the case when the usual geometric assumptions are not satisfied.
