In this paper the concepts of lower mild and upper mild solutions combined with a fixed point theorem for condensing maps and the semigroup theory are used to investigate the
The Schauder Fixed Point Theorem is, undoubtedly, one of the most impor- tant theorems of nonlinear analysis.. Theorem 1.1 (Schauder) Let M be a nonempty closed bounded convex sub-
In this paper, a recent Frigon nonlinear alternative for contractive multivalued maps in Fr´ echet spaces, combined with semigroup theory, is used to investigate the existence
