Criteria for finite generation of topological full groups
Connections between groupoid homology and topological full groups
Abstract
It is proven that Matui's AH~conjecture is true for Katsura--Exel--Pardo groupoids associated to integral matrices and . This conjecture relates the topological full group of an ample groupoid with the homology groups of the groupoid. We also give a criterion under which the topological full group is finitely generated.
