Resumen: Given a group action by homeomorphisms on a topological space, one can wonder under which conditions two points have isomorphic stabilisers. We will answer this question in the case where the action is "micro-supported" and "sufficiently minimal", a class that includes many interesting examples, such as the Grigorchuk group, Thompson`s groups and topological full groups of Cantor minimal systems.
