ABSTRACT. In this note we investigate the hypercentral units in integral group rings ZG, where G is not necessarily torsion. One of the main results obtained is the following (Theorem 3.5): if the set of torsion elements of G is a subgroup T of G and if Z2(U) is not contained in CU (T), then T is either an Abelian group of exponent 4 or a Q ∗ group. This extends our earlier result on torsion group rings.
We classify groups G such that the unit group U-1 (ZG) is hypercentral. In the second part, we class...
