ejde-496	Wang, Shaoqing; Yang, Jiazhong	Period functions and critical periods of piecewise linear system	2020	12	.pdf	application/pdf	4097	227	76	Some orbits of piecewise linear system X in Section 3 In more detail, the trajectories of X = (X1, X2) in Figure 5 show that A6B4, B3B4, B3A3, A4B2, B1B2 and B1A1 all consist of sliding or escaping points (see the dashed lines in Figure 6), consequently, the closed orbits can only intersect three lines: PA5A6, A3A4 and A1A2Q. , nm, there exist two types of piecewise linear systems: one has a period annulus possessing exactly n critical periods; the other has m period annuli possessing exactly n1, n2, . . .	cache/ejde-496.pdf	txt/ejde-496.txt
