Rational points in coarse moduli spaces and twisted representations
Fabian Korthauer, Stefan Schröer
We study moduli spaces and moduli stacks for representations of associative algebras in Azumaya algebras, in rather general settings. We do not impose any stability condition and w…

Arithmetic Representation Growth of Virtually Free Groups
Fabian Korthauer
We adapt methods from quiver representation theory and Hall algebra techniques to the counting of representations of virtually free groups over finite fields. This gives rise to th…
