Grazing-sliding bifurcations in planar ${\mathbb{Z}}_2$-symmetric Filippov systems

Xingwu Chen, Zhihao Fang, Tao Li

This paper aims to explore the effect of ${\mathbb{Z}}_2$-symmetry on grazing-sliding bifurcations in planar Filippov systems. We consider the scenario where the unperturbed system i…
