High transitivity for more groups acting on trees

Pierre Fima, François Le Maître, Soyoung Moon, Yves Stalder

Published 2020-03-24Version 1

We establish a new sharp sufficient condition for groups acting on trees to be highly transitive. This give new examples of highly transitive groups, including icc non-solvable Baumslag-Solitar groups, thus answering a question of Hull and Osin.
