Isomorphism questions for metric ultraproducts of finite quasisimple groups
Jakob Schneider
New results on metric ultraproducts of finite simple groups are established. We show that the isomorphism type of a simple metric ultraproduct of groups () for…

On groups with unbounded Cayley graphs
Jakob Schneider
We show that every non-trivial compact connected group and every non-trivial general or special linear group over an infinite field admits a generating set such that the associated…
