Evolution Inclusions with State-Dependent Maximal Monotone Operators

The existence of an absolutely continuous solution of a differential inclusion whose right-hand side containsa time- and state-dependent maximal monotone operator and a nonconvex perturbation is proved in a Hilbert space.The proofs are based on our comparison theorems for inclusions with maximal monotone operators and a fixed pointtheorem for multivalued mappings. This approach allows us to extend the class of inclusions with maximal monotoneoperators for which existence theorems are valid and, as a result, to obtain significant results of this kind.
