Gijs Heuts, Irakli Patchkoria
We study a family of generalizations of the notion of Euler characteristic of discrete groups (or of orbifolds, depending on one's perspective) indexed on the natural numbers. For…

On the Farrell--Tate -theory of
Naomi Andrew, Irakli Patchkoria
Using Lück's Chern character isomorphism we obtain a general formula in terms of centralisers for the -adic Farrell--Tate -theory of any discrete group with a finite cla…
