To study the global dynamics of [Formula: see text] completely, since the dynamics of [Formula: see text] is very simple, we are only interested in the global dynamics of [Formula: see text] in this paper. Firstly, we use Briot\u2013Bouquet transformations and normal sector methods to discuss these degenerate equilibria at infinity. Secondly, we discuss the number of limit cycles completely. Then, the sufficient and necessary conditions of existence of the heteroclinic loop are found. To estimate the upper bound of the heteroclinic loop bifurcation function on parameter space, a result on the amplitude of a unique limit cycle of a discontinuous Li\u00e9nard system is given. Finally, the complete bifurcation diagram and all global phase portraits are presented. The global dynamic property of system [Formula: see text] is totally different from systems [Formula: see text]. <\/jats:p>","DOI":"10.1142\/s0218127420501059","type":"journal-article","created":{"date-parts":[[2020,7,1]],"date-time":"2020-07-01T09:25:33Z","timestamp":1593595533000},"page":"2050105","source":"Crossref","is-referenced-by-count":1,"title":["Global Dynamics of a Planar Filippov System with Symmetry"],"prefix":"10.1142","volume":"30","author":[{"given":"Hongjie","family":"Pan","sequence":"first","affiliation":[{"name":"College of Mathematics and Computer Science, Fuzhou University, Fuzhou, Fujian 350116, P.
