Braid stability and the Hofer metric
Marcelo R. R. Alves, Matthias Meiwes
In this article we show that the braid type of a set of -periodic orbits of a non-degenerate Hamiltonian diffeomorphism on a surface is stable under perturbations which are suff…

Hofer's geometry and topological entropy
Arnon Chor, Matthias Meiwes
In this article we study persistence features of topological entropy and periodic orbit growth of Hamiltonian diffeomorphisms on surfaces with respect to Hofer's metric. We exhibit…
