This paper is concerned with 1-parameter families of periodic solutions of piecewise smooth planar vector fields, when they behave like a center of smooth vector fields. We are interested in finding a separation boundary for a given pair of smooth systems in such a way that the discontinuous system, formed by the pair of smooth systems, has a continuum of periodic orbits. In this case we call the separation boundary as a center boundary. We prove that given a pair of systems that share a hyperbolic focus singularity p(0), with the same orientation and opposite stability, and a ray Sigma(0) with endpoint at the singularity p(0), we can find a smooth manifold Omega such that Sigma(0) boolean OR [p(0)] boolean OR Omega is a center boundary. The maximum number of such manifolds satisfying these conditions is five. Moreover, this upper bound is reached. (C) 2016 Elsevier Inc. All rights reserved. (AU) | |
