报告摘要：For piecewise-smooth dynamical systems with small parameters, the cases with multiple roots of the degenerate equations have been studied. Because the classical boundary layer function method and Fenichel’s three theorems are no longer applicable, constructing the asymptotic solution is very difficult. In this talk, by using asymptotic method, geometric theory and numerical method, multi-scale smooth asymptotic solutions are constructed and the existence of a contrast structure solution is proved.
