Abstract

This project concerns on global aspects of nonsmooth differential equations, Lipschitz continuous and discontinuous. It is divided in 3 main subjects: Bifurcation of Limit Cycles, Bifurcation of Invariant Tori and Shilnikov Connections in Filippov Systems. Each subject presents several subprojects, which are concerned on distinct topics such as: averaging theory and Melnikov functions, tangential polycycles, Hopf and Neimark-Sacker bifurcation, KAM theory, Shilnikov connections and chaos in real models, and regularization of Filippov systems.
