Two results on end spaces of infinite type surfaces

Geometric Topology 2022-03-16 v2

Abstract

We answer two questions about the topology of end spaces of infinite type surfaces and the action of the mapping class group that have appeared in the literature. First, we give examples of infinite type surfaces with end spaces that are not self-similar, but a unique maximal type of end, either a singleton or Cantor set. Secondly, we use an argument of Tsankov to show that the "local complexity" relation \preccurlyeq on end types gives an equivalence relation that agrees with the notion of being locally homeomorphic.
