Abstract:
We derive necessary and sufficient conditions for periodic trajectories of billiards within an ellipse in the Minkowski plane in terms of an underlying elliptic curve. Equivalent conditions are derived in terms of polynomial-functional equations as well. The corresponding polynomials are related to the classical extremal polynomials. Similarities and differences with respect to the previously studied Euclidean case are indicated.
The research of V.D. and M.R. was supported by the Discovery Project #DP190101838 Billiards within
confocal quadrics and beyond from the Australian Research Council and Project #174020 Geometry and
Topology of Manifolds, Classical Mechanics and Integrable Systems of the Serbian Ministry of Education,
Technological Development and Science.
