Resumen
This paper is concerned with a codimension analysis of a two-fold singularity of piecewise smooth planar vector fields, when it behaves itself like a center of smooth vector fields (also called nondegenerate σ-center). We prove that any nondegenerate σ-center is σ-equivalent to a particular normal form Z0. Given a positive integer number k we explicitly construct families of piecewise smooth vector fields emerging from Z0 that have k hyperbolic limit cycles bifurcating from the nondegenerate σ-center of Z0 (the same holds for k=∞). Moreover, we also exhibit families of piecewise smooth vector fields of codimension k emerging from Z0. As a consequence we prove that Z0 has infinite codimension. © 2013 Elsevier Masson SAS. 102 1 36 47 Arrowsmith, D.K., Place, C.M., (1990) An Introduction to Dynamical Systems, , Cambridge University Press Buzzi, C.A., de Carvalho, T., Teixeira, M.A., On three-parameter families of Filippov systems - the fold-saddle singularity (2012) Int.
