Orders of units in integral group rings and blocks of defect $1$

Mauricio Caicedo, Leo Margolis

We show that if the Sylow $p$ -subgroup of a finite group $G$ is of order $p$ , then the normalized unit group of the integral group ring of $G$ contains a normalized unit of order $…

The twisted group ring isomorphism problem over fields

L. Margolis, O. Schnabel

Similarly to how the classical group ring isomorphism problem asks, for a commutative ring $R$ , which information about a finite group $G$ is encoded in the group ring $R G$ , the tw…
