Analytic symplectomorphisms displaying minimal ergodicity on the sphere, cylinder and disk

Dynamical Systems 2026-03-09 v1

Abstract

We construct analytic symplectomorphisms on the sphere, the disk and the cylinder which are minimally ergodic (only 3 ergodic measures). To achieve this, we apply and generalize a principle introduced by Berger, based on the Approximation by Conjugacy method of Anosov-Katok.
