Infinite end-devouring sets of rays with prescribed start vertices

Combinatorics 2017-04-24 v1

Abstract

We prove that every end of a graph contains either uncountably many disjoint rays or a set of disjoint rays that meet all rays of the end and start at any prescribed feasible set of start vertices. This confirms a conjecture of Georgakopoulos.
