We study one-parameter families of systems Zε passing through a specific model Z0 whose phase portrait is foliated by invariant nested tori. For each positive integer k we, explicitly, construct a family Zε k possessing exactly k nested tori.4008-4029engBifurcationInvariant toriLimit cyclesNonsmooth vector fieldArtigo10.1016/j.jde.2016.06.015Acesso restrito2-s2.0-84978999423
