“…Working in the implicit function framework [10,11], we have computed in Subsection 4.1, using the (approximate) steady-state solution obtained in [1,6,9], the jump manifold 13, comprising information about all jumps in the dynamical system 1. Our formalism, described in Section 4 -built on an idea to use a differential condition to detect vertical tangencies, due to Kalmár-Nagy and Balachandran [8] -can be applied to arbitrary steady-state solution.…”
