We focus our attention on the existence of two-point crossing limit cycles, which intersect the switching line at two points. We obtain sufficient conditions under which the system has two two-point crossing limit cycles which intersect only one of the two rays. Moreover, we construct examples to show that this class of systems can have two, three or four two-point crossing limit cycles. <\/jats:p>","DOI":"10.1142\/s0218127424500494","type":"journal-article","created":{"date-parts":[[2024,4,9]],"date-time":"2024-04-09T08:35:51Z","timestamp":1712651751000},"source":"Crossref","is-referenced-by-count":3,"title":["Crossing Limit Cycles in Planar Piecewise Linear Systems Separated by a Nonregular Line with Node\u2013Node Type Critical Points"],"prefix":"10.1142","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-1502-600X","authenticated-orcid":false,"given":"Liping","family":"Sun","sequence":"first","affiliation":[{"name":"Department of Mathematics, Sichuan University, Chengdu, Sichuan 610064, P.
