|Title:||Trees and reflection groups|
|Abstract:||We define a reflection in a tree as an involutive automorphism whose set of fixed points is a geodesic and prove that, for the case of a homogeneous tree of degree 4k, the topological closure of the group generated by reflections has index 2 in the group of automorphisms of the tree.|
