Only their cardinality can prevent groups from being quotients of weakly branch groups

J. Moritz Petschick

It is a well-known fact that every proper quotient of a branch group is a virtually abelian group. We record that every group of cardinality at most $2^{ℵ_{0}}$ is a quotient of…

Representation zeta functions of split extensions of $S L_{2}^{m} (O)$

J. Moritz Petschick, Margherita Piccolo

We consider the representation growth of split extensions of $S L_{2}^{m} (O)$ . We prove that the corresponding representation zeta functions factor as a product of the representation ze…
