Abstract:The Conley theory has a tool to guarantee the existence of periodic trajectories in isolating neighborhoods of semi-dynamical systems; this tool is the main result of [18]. We prove that the positive trajectories generated by a piecewise-smooth vector field Z = (X, Y ) defined in a closed manifold of dimension three without the scape region produce a semi-dynamical system. Thus, supported by [18], we have a mechanism to warrant the existence of periodic orbits in this class of piecewise-smooth vector fields.
