Abstract
The paper contains several results relating to deformation techniques in critical point theory for continuous functions on metric spaces, including two deformation theorems, an extension of the mountain pass theorem and a dense solvability theorem for potential set-valued operators associated with critical points of Lipschitz perturbations of quadratic functional in Hilbert spaces.
