In particular, for each nonlinear oscillator given in [Itoh & Chua, 2008], we show the existence of an infinite family of invariant manifolds and that the dynamics on such manifolds can be modeled without resorting to discontinuous models. Our approach provides topologically equivalent continuous models with one dimension less but with one extra parameter associated to the initial conditions. It is possible to justify the periodic behavior exhibited by three-dimensional memristor oscillators, by taking advantage of known results for planar continuous piecewise linear systems. <\/jats:p> The analysis developed not only confirms the numerical results contained in previous works [Messias et al., 2010; Scarabello & Messias, 2014] but also goes much further by showing the existence of closed surfaces in the state space which are foliated by periodic orbits. The important role of initial conditions that justify the infinite number of periodic orbits exhibited by these models, is stressed. The possibility of unsuspected bistable regimes under specific configurations of parameters is also emphasized. <\/jats:p>","DOI":"10.1142\/s0218127417300221","type":"journal-article","created":{"date-parts":[[2017,7,4]],"date-time":"2017-07-04T03:24:48Z","timestamp":1499138688000},"page":"1730022","source":"Crossref","is-referenced-by-count":15,"title":["On Discontinuous Piecewise Linear Models for Memristor Oscillators"],"prefix":"10.1142","volume":"27","author":[{"given":"Andr\u00e9s","family":"Amador","sequence":"first","affiliation":[{"name":"Departamento de Ciencias Naturales y Matem\u00e1ticas, Pontificia Universidad Javeriana-Cali, Calle 18, No. 118-250, Santiago de Cali, Colombia"}]},{"given":"Emilio","family":"Freire","sequence":"additional","affiliation":[{"name":"Departamento de Matem\u00e1tica Aplicada II, Universidad de Sevilla, Escuela T\u00e9cnica Superior de Ingenier\u00eda, Camino de los Descubrimientos s\/n, 41092 Sevilla, Spain"}]},{"given":"Enrique","family":"Ponce","sequence":"additional","affiliation":[{"name":"Departamento de Matem\u00e1tica Aplicada II, Universidad de Sevilla, Escuela T\u00e9cnica Superior de Ingenier\u00eda, Camino de los Descubrimientos s\/n, 41092 Sevilla, Spain"}]},{"given":"Javier","family":"Ros","sequence":"additional","affiliation":[{"name":"Departamento de Matem\u00e1tica Aplicada II, Universidad de Sevilla, Escuela T\u00e9cnica Superior de Ingenier\u00eda, Camino de los Descubrimientos s\/n, 41092 Sevilla, Spain"}]}],"member":"219","published-online":{"date-parts":[[2017,7,3]]},"reference":[{"key":"S0218127417300221BIB001","doi-asserted-by":"publisher","DOI":"10.1109\/TCSI.2016.2564738"},{"key":"S0218127417300221BIB002","doi-asserted-by":"publisher","DOI":"10.1142\/S0218127414501521"},{"key":"S0218127417300221BIB003","doi-asserted-by":"publisher","DOI":"10.1109\/TCT.1971.1083337"},{"key":"S0218127417300221BIB004","doi-asserted-by":"publisher","DOI":"10.1142\/S021812741230011X"},{"key":"S0218127417300221BIB005","doi-asserted-by":"publisher","DOI":"10.1109\/TCSI.2010.2097731"},{"key":"S0218127417300221BIB006","doi-asserted-by":"publisher","DOI":"10.1109\/JETCAS.2015.2426494"},{"key":"S0218127417300221BIB007","doi-asserted-by":"publisher","DOI":"10.1109\/TCSI.2016.2590948"},{"key":"S0218127417300221BIB008","volume":"99","author":"Corinto F.","year":"2017","journal-title":"IEEE Trans.
