Periodic solutions of nonlinear evolution inclusions
The authors establish the existence of periodic trajectories for a class of nonlinear, time-varying evolution inclusions, in which the multivalued term is nonconvex-valued. This result partially extends a recent work of \textit{I. Vrabie} [Proc. Am. Math. Soc. 109, 653-661 (1990; Zbl 0701.34074)]. An example of a parabolic system is also presented in detail.
