Título: On Heteroclinic Orbits Bifurcating from a Degenerate T-Singularity

Resumo: This talk is devoted to the characterization of the local sliding and crossing dynamics around an invisible two-fold singularity (T-singularity) in 3D Filippov systems which presents a degeneracy arising from the contact between the tangency fold curves of a system with the switching manifold. More specifically, we show that, when the contact between such curves is 2 or 3 at this point, then it presents a nonsmooth diabolo emanating from it which has one branch or two branches, respectively, and if one consider small perturbations in the cubic case, then it gives rise to an invariant surface foliated by crossing heteroclinic orbits between generic T-singularities bifurcating from such degenerate singularity. This is a joint work with O. A. R. Cespedes and R. Cristiano.
