Periodic solutions in a given set of differential systems

[摘要] The existence of a periodic solution in a given set of Caratheodory differential systems is studied. The proof of the main statement is based on the Wazewski-type approach jointly with the degree arguments. An illustrating example is supplied, and a comparison with the analogous results of other authors is indicated. (C) 2001 Elsevier Science.
