Topological models of finite type for tree almost automorphism groups
Roman Sauer, Werner Thumann
We show that tree almost automorphism groups, including Neretin groups, satisfy the analogue of the -finiteness condition in the world of totally disconnected groups: The…
Operad groups and their finiteness properties
Werner Thumann
We propose a new unifying framework for Thompson-like groups using a well-known device called operads and category theory as language. We discuss examples of operad groups which ha…
L2-invisibility of symmetric operad groups
Werner Thumann
We show a homological result for the class of planar or symmetric operad groups: We show that under certain conditions, group (co)homology of such groups with certain coefficients…
Operad groups as a unified framework for Thompson-like groups
Werner Thumann
We propose a new unified framework for Thompson-like groups using a well-known device called operads and category theory as language. We discuss examples of operad groups which hav…
L2-invisibility and a class of local similarity groups
Roman Sauer, Werner Thumann
In this note we show that the members of a certain class of local similarity groups are l2-invisible, i.e. the non-reduced group homology of the regular unitary representation vani…
