报告提纲:
The index of a singular point is an important quantity which characterizes the topological structure of the singular point. In this talk, we will extend the index of singular point to piecewise smooth differential system. Using Cauchy index, we deduce an algebraic method to calculate the index of singular point for piecewise smooth differential system.
