Set-valued perturbation for time dependent subdifferential operator

Soumia Saïdi, Mustapha Fateh Yarou



In a separable Hilbert space, we consider an evolution inclusion involving time-dependent subdifferential of a proper convex lower semicontinuous function with a set-valued perturbation depending on both time and state variable. We prove, under a compactness condition on the perturbation, that there exists at least one absolutely continuous solution.
