Units in Non-Commutative Orders

Research output: ThesisPhD Thesis


For a ring R with unity 1, we denote by U(R) the unit group of R, i.e. the group of invertible elements in R. For decades one has investigated the unit group of an integral group ring Z[G] of a group G. These rings are very interesting algebraic structures, because of their obvious relationship with group theory and ring theory and because the investigations in the structure also involve for example the theory of fields, linear algebra, alge- braic topology, algebraic number theory and algebraic K-theory. Hence the research in group rings is a subject where many branches of algebra meet. In the study of group rings the knowledge of the unit group is crucial, but a complete description of the unit group in terms of generators and relations still seems out of reach, even for special classes of groups.
