Minimal displacement set for CAT(0) cubical complexes

Abstract

We investigate the structure of the minimal displacement set in CAT(0) cubical complexes. We show that such set is convex, it is locally endowed with a CAT(0) metric and it is simply connected.

Comments

It turns out there is counterexample according to which the minimal displacement set of a hyperbolic isometry acting on a CAT(0) cubical complex is not convex
