Hopf-like bifurcations induced by hysteresis and time-delay near monodromic tangential singularities
Douglas D. Novaes, Paulo Santana, David J. W. Simpson
We investigate planar piecewise-analytic vector fields, focusing on the merged focus and other monodromic tangential singularities when hysteresis or time-delay is incorporated int…

Boundary Hopf bifurcations in three-dimensional Filippov systems
David J. W. Simpson
For piecewise-smooth ordinary differential equations, the occurrence of a Hopf bifurcation on a switching surface is known as a boundary Hopf bifurcation. Boundary Hopf bifurcation…
