Morse and stable subgroups via the coset intersection complex
arXiv:2603.29158
Abstract
In this note, we study the equivalence of Morse and stable subgroups in the framework of the coset intersection complex. Under certain conditions on a coset intersection complex of a group, we prove that infinite-index Morse subgroups are stable.
