On typical homoclinic-like loops in 3D Filippov systems

WebA Hopf bifurcation is different in character to the previous three bifurcations and represents a situation where a system that is steady with time suddenly begins to oscillate as a … WebIn this paper we study tangency bifurcations of invariant manifolds of Poincaré maps on global sections of vector fields in $\mathbb{R}^2$ and $\mathbb{R}^3$. At such a bifurcation the manifold becomes tangent to the section, which results in a qualitative change of the Poincaré map while the underlying flow itself does not undergo a bifurcation.
