Description of the structure of DG--algebras via characters on a groupoid
Andronick Arutyunov, Oleg Muravev
We construct a description of graded derivations in group algebras. Using this result for arbitrary graduation of the group algebra, we describe all possible structures of DG algeb…
A combinatorial view on derivations in bimodules
Andronick Arutyunov
This paper is devoted to derivations in bimodules over group rings using previously proposed methods which are related to character spaces over groupoids. The theorem describing th…
Derivations of group rings for finite and FC groups
Andronick Arutyunov, Leo Kosolapov
In this paper we establish decomposition theorems for derivations of group rings. We provide a topological technique for studying derivations of a group ring in case has…
On -derivations of group algebra as category characters
Aleksandr Alekseev, Andronick Arutyunov, Sergei Silvestrov
For the space of -derivations of the group algebra of discrete countable group , the decomposition theorem for the space of -derivations, genera…
Derivations of Group Algebras
A. A. Arutyunov, A. S. Mishchenko, A. I. Shtern
In the paper, a method of describing the outer derivations of the group algebra of a finitely presentable group is given. The description of derivations is given in terms of charac…
