摘要：We will talk about center and its isochronicity for planar switching systems. We give some sufficient conditions for thesystem to have a regular isochronous center at the origin and, on the other hand, construct a switching system with anirregular isochronous center at the origin. We give a computation method for periods of periodic orbits near the center and use the method to discuss a switching Bautin system for center conditions and isochronicity conditions.
