Rigorous computation of periodic solutions and Floquet multipliers in DDEs with time-forced discontinuities
13 octobre 2020 de 10 h 00 à 11 h 00 (heure de Montréal/HNE) Réunion Zoom
I will present some recent work on rigorous computation of periodic solutions for delay differential equations with impulse effects. At fixed moments in time, the state of such a system is reset and solutions become discontinuous. Once a periodic solution of such a system has been computed, its Floquet spectrum can be rigorously computed by discretization of the monodromy operator (period map) and some technical error estimates. As an application, we compute a branch of periodic solutions in the pulse-harvested Hutchinson equation and examine its stability.
