Unit groups of integral finite group rings with no noncyclic abelian finite subgroups

Martin Hertweck

It is shown that in the units of augmentation one of an integral group ring $Z G$ of a finite group $G$ , a noncyclic subgroup of order $p^{2}$ , for some odd prime $p$ , exi…

The orders of torsion units in integral group rings of finite solvable groups

Martin Hertweck

It is shown that for any torsion unit of augmentation one in the integral group ring $Z G$ of a finite solvable group $G$ , there is an element of $G$ of the same order.

Class-preserving automorphisms and the normalizer property for Blackburn groups

Martin Hertweck, Eric Jespers

For a group $G$ , let $U$ be the group of units of the integral group ring $Z G$ . The group $G$ is said to have the normalizer property if $N_{U} (G) = Z (U) G$ . It i…
