Hofer's distance between eggbeaters and autonomous Hamiltonian diffeomorphisms on surfaces

Symplectic Geometry 2022-06-01 v1

Abstract

Let Σ\Sigma be a compact surface of genus g1g \geq 1 equipped with an area form. We construct eggbeater Hamiltonian diffeomorphisms which lie arbitrarily far in the Hofer metric from the set of autonomous Hamiltonians. This result is already known for g2g \geq 2 (our argument provides an alternative, very simple construction compared to previous publications) while the case g=1g = 1 is new.
