Weil zeta functions of group representations over finite fields

Ged Corob Cook, Steffen Kionke, Matteo Vannacci

In this article we define and study a zeta function - similar to the Hasse-Weil zeta function - which enumerates absolutely irreducible representations over finite fields of…

Counting irreducible modules for profinite groups

Ged Corob Cook, Steffen Kionke, Matteo Vannacci

This article is concerned with the representation growth of profinite groups over finite fields. We investigate the structure of groups with uniformly bounded exponential represent…

Probabilistic finiteness properties for profinite groups

Ged Corob Cook, Matteo Vannacci

We introduce various probablistic finiteness conditions for profinite groups related to positive finite generation (PFG). We investigate completed group rings which are PFG as modu…

On the asymptotic behaviour of the number of Beauville and non-Beauville -groups

Gustavo A. Fernández-Alcober, Şükran Gül, Matteo Vannacci

We find asymptotic lower bounds for the numbers of both Beauville and non-Beauville -generator finite -groups of a fixed order, which turn out to coincide with the best known…

On hereditarily just infinite profinite groups with complete Hausdorff dimension spectrum

Yiftach Barnea, Matteo Vannacci

We prove that the inverse limit of certain iterated wreath products in product action have complete Hausdorff dimension spectrum with respect to their unique maximal filtration of…

On self-similar finite -groups

Azam Babai, Khadijeh Fathalikhani, Gustavo A. Fernandez-Alcober +1

In this paper, we address the following question: when is a finite -group self-similar, i.e. when can be faithfully represented as a self-similar group of automorphisms…
