Integral group rings with all central units trivial
arXiv:1606.06860 · doi:10.1016/j.jpaa.2013.12.010
Abstract
The object of study in this paper is the finite groups whose integral group rings have only trivial central units. Prime-power groups and metacyclic groups with this property are characterized. Metacyclic groups are classified according to the central height of the unit groups of their integral group rings.
