讨论了一类中心型半连续动力系统的阶1周期解和阶2周期解的存在性、个数及其稳定性,给出该中心型系统存在唯一、两个、无穷多个阶1周期解和阶2周期解的条件,并给出了相应理论结果的数值模拟.
The paper discussed a class of semi-continuous dynamical system with cen- ter equilibrium and the existences , number and stability of order-lperiodic solution and order2periodic solution. The conditions that the system has unique, two, infinite order-1 periodic solutions and order-2 periodic solution are given, respectively, and the corresponding numericalsimulations are provided to verify the results.
