Universal measure for Poncelet-type theorems

Dynamical Systems 2016-10-04 v1 Differential Geometry

Abstract

We give a simple proof of the Emch closing theorem by introducing a new invariant measure on the circle. Special cases of that measures are well-known and have been used in the literature to prove Poncelet's and Zigzag theorems. Some further generalizations are also obtained by applying the new measure.
