报告摘要 Abstract:

We talk about global dynamics of an unfolding of regular-saddle-node with saddle structure. In this unfolding both perturbations of vector fields and switching manifold are considered. Bifurcation of boundary equilibria, tangency points, pseudo equilibria and heteroclinic orbits are explored for general parameters and some bifurcation phenomena appear only for non-sufficiently small parameters.
