Existence of periodic solution of order one of planar impulsive autonomous system. (English) Zbl 1088.34040
The authors investigate the state-dependent impulsive differential equations wich have no explicit solution. Sufficient conditions for the existence of a periodic solution of order one for such systems are proved.
