Papageorgiou, Nikolaos S. On evolution inclusions associated with time dependent convex subdifferentials. (English) Zbl 0711.34076 Commentat. Math. Univ. Carol. 31, No. 3, 517-527 (1990). Summary: We study evolution inclusions driven by a time varying convex subdifferential and a multivalued perturbation. We have two existence theorems; one for nonconvex valued perturbations and the other for convex valued perturbations. Then we compare those two solution sets (“relaxation theorem”). Our results extend earlier ones by Attouch- Damlamian, Aubin-Cellina, Moreau, Watanabe and Yotsutani.
