Heteroclinic solutions in singularly perturbed discontinuous differential equations: a non-generic case

Abstract

We derive Melnikov type conditions for the persistence of heteroclinic solutions in perturbed slowly varying discontinuous differential equations. Opposite to [J. Differential Equations 400(2024), 314–375] we assume that the unperturbed (frozen) equation has a parametric system of heteroclinic solutions and extend a result in [SIAM J. Math. Anal. 18(1987), 612–629] and [SIAM J. Math. Anal. 19(1988), 1254–1255] to higher dimensional non-Hamiltonian discontinuous singularly perturbed differential equations.
