Under the antiparallelism hypothesis, it is known that the system undergoes the so-called pseudo-Hopf bifurcation (pH). In this paper, we consider a particular position of the antiparallel vectors to yield a two-parametric unfolding of the TS. The bifurcation analysis gives us, besides the curve of pH bifurcation points, a curve of saddle-node bifurcation points for crossing limit cycles. We call this phenomenon the pseudo-Bautin bifurcation, since it exhibits the exact same behavior as the Bautin bifurcation for smooth dynamical systems. <\/jats:p>","DOI":"10.1142\/s0218127422501206","type":"journal-article","created":{"date-parts":[[2022,6,30]],"date-time":"2022-06-30T08:43:59Z","timestamp":1656578639000},"source":"Crossref","is-referenced-by-count":8,"title":["Pseudo-Bautin Bifurcation in 3D Filippov Systems"],"prefix":"10.1142","volume":"32","author":[{"given":"Juan","family":"Castillo","sequence":"first","affiliation":[{"name":"Departamento de Matem\u00e1ticas, Universidad de Sonora, M\u00e9xico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fernando","family":"Verduzco","sequence":"additional","affiliation":[{"name":"Departamento de Matem\u00e1ticas, Universidad de Sonora, M\u00e9xico"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2022,6,30]]},"reference":[{"key":"S0218127422501206BIB001","doi-asserted-by":"publisher","DOI":"10.1016\/j.physd.2011.11.020"},{"key":"S0218127422501206BIB002","doi-asserted-by":"publisher","DOI":"10.1016\/j.physd.2013.01.002"},{"key":"S0218127422501206BIB003","doi-asserted-by":"publisher","DOI":"10.1088\/0951-7715\/27\/3\/585"},{"key":"S0218127422501206BIB004","doi-asserted-by":"publisher","DOI":"10.1007\/s00332-015-9251-z"},{"key":"S0218127422501206BIB005","doi-asserted-by":"publisher","DOI":"10.3934\/dcds.2019215"},{"key":"S0218127422501206BIB006","doi-asserted-by":"publisher","DOI":"10.1063\/5.0014830"},{"key":"S0218127422501206BIB007","doi-asserted-by":"publisher","DOI":"10.1016\/j.sysconle.2010.07.006"},{"key":"S0218127422501206BIB008","doi-asserted-by":"publisher","DOI":"10.1137\/100801846"},{"key":"S0218127422501206BIB009","doi-asserted-by":"publisher","DOI":"10.1142\/S0218127418501067"},{"key":"S0218127422501206BIB010","doi-asserted-by":"publisher","DOI":"10.1007\/s11071-019-04851-8"},{"key":"S0218127422501206BIB011","doi-asserted-by":"publisher","DOI":"10.1016\/j.jde.2019.08.024"},{"key":"S0218127422501206BIB012","doi-asserted-by":"publisher","DOI":"10.1016\/j.jmaa.2019.123692"},{"key":"S0218127422501206BIB013","doi-asserted-by":"publisher","DOI":"10.1007\/978-94-015-7793-9"},{"key":"S0218127422501206BIB014","doi-asserted-by":"publisher","DOI":"10.1142\/S0218127407017367"},{"key":"S0218127422501206BIB015","doi-asserted-by":"publisher","DOI":"10.1142\/S0218127409023147"},{"key":"S0218127422501206BIB016","doi-asserted-by":"publisher","DOI":"10.1016\/j.jde.2015.08.013"},{"key":"S0218127422501206BIB017","doi-asserted-by":"publisher","DOI":"10.1016\/j.jde.2010.11.016"},{"key":"S0218127422501206BIB018","doi-asserted-by":"publisher","DOI":"10.1142\/S0218127421500255"},{"key":"S0218127422501206BIB019","doi-asserted-by":"publisher","DOI":"10.1137\/08073113X"},{"key":"S0218127422501206BIB020","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-0348-0657-2"},{"key":"S0218127422501206BIB021","doi-asserted-by":"publisher","DOI":"10.1007\/s00332-015-9244-y"},{"key":"S0218127422501206BIB022","doi-asserted-by":"publisher","DOI":"10.1142\/S0218127415300086"},{"key":"S0218127422501206BIB023","doi-asserted-by":"publisher","DOI":"10.1016\/0022-0396(90)90106-Y"},{"key":"S0218127422501206BIB024","doi-asserted-by":"publisher","DOI":"10.1006\/jmaa.1993.1226"}],"container-title":["International Journal of Bifurcation and Chaos"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.worldscientific.com\/doi\/pdf\/10.1142\/S0218127422501206","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,6,30]],"date-time":"2022-06-30T08:44:23Z","timestamp":1656578663000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.worldscientific.com\/doi\/10.1142\/S0218127422501206"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,6,30]]},"references-count":24,"journal-issue":{"issue":"08","published-print":{"date-parts":[[2022,6,30]]}},"alternative-id":["10.1142\/S0218127422501206"],"URL":"https:\/\/doi.org\/10.1142\/s0218127422501206","relation":{},"ISSN":["0218-1274","1793-6551"],"issn-type":[{"value":"0218-1274","type":"print"},{"value":"1793-6551","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022,6,30]]},"article-number":"2250120"}}
