ABSTRACT
Using variational techniques, we study the dynamics of the breathing circle billiard. We prove the existence of Aubry–Mather sets, which contain infinite subharmonic and generalized quasi-periodic solutions, in arbitrarily high energy regions. This is under the assumption that the boundary motion is a periodic function. Additionally, our method provides a feasible approach to small twist problems and can be applied to some classical impact systems.
