Locally tame plane polynomial automorphisms
Joost Berson, Adrien Dubouloz, Jean-Philippe Furter +1
For automorphisms of a polynomial ring in two variables over a domain R, we show that local tameness implies global tameness provided that every 2-generated invertible R-module is…

A Characterization of Semisimple Plane Polynomial Automorphisms
Jean-Philippe Furter, Stefan Maubach
It is well-known that an element of the linear group ${\rm GL}_n(\C)$ is semisimple if and only if its conjugacy class is Zariski closed. The aim of this paper is to show that the…
