Title: Covering number for reflections in trees
Author: Talpo, Humberto Luiz
Firer, Marcelo
Abstract: We define a reflection in a tree to be an involutive automorphism whose set of fixed points is a geodesic, and we prove that, for the case of a homogeneous tree of even degree, the group of even automorphisms may be covered by at most seven reflections.
