Title：

Synchronization And Control for Differential Equations with Discontinuous State on the Right-Hand Sides

Abstract：

In this talk, we mainly focus on the existence of Filippov solution of neural networks with discontinuous activation functions and mixed time-delays (time-varying discrete delay and infinite-time distributed delay) and some synchronization control methods for differential equations with discontinuous state on the right-hand sides. Firstly, sufficient conditions for the global existence of Filippov solutions to neural networks with discontinuous activation functions and the mixed delays are given by strict mathematical proof. Then, some novel control schemes are designed to guarantee that several discontinuous chaotic systems can be driven to realize synchronization, including exponential synchronization and finite-time synchronization.
