A note on Hybrid Routh reduction for time-dependent Lagrangian systems

Mathematical Physics 2020-03-18 v1 math.MP

Abstract

This note discusses Routh reduction for hybrid time-dependent mechanical systems. We give general conditions on whether it is possible to reduce by symmetries a hybrid time-dependent Lagrangian system extending and unifying previous results for continuous-time systems. We illustrate the applicability of the method using the example of a billiard with moving walls.
