Gabor, Grzegorz Periodic solutions for nonautonomous differential equations and inclusions in tubes. (English) Zbl 1076.34046 Abstr. Appl. Anal. 2004, No. 12, 1057-1079 (2004). The existence of periodic solutions for differential inclusions is studied. All problems are considered on some subsets of Euclidean spaces. Instead of upper semi-continuity other suitable assumptions are introduced. Firstly, the problem of existence of viable solutions is taken up. Then very interesting periodic problems are solved.
