The Almost Finite--Purely Infinite Dichotomy\\ for Minimal Amenable Ample Groupoids
We answer, in the principal setting, a question of Matui on the almost finite--purely infinite dichotomy for minimal amenable ample groupoids. We prove that a second-countable Hausdorff minimal principal topologically amenable ample groupoid with Cantor unit space is strongly almost finite if and on
