Semigroup algebras of submonoids of polycyclic-by-finite groups and maximal orders

Isabel Goffa, Eric Jespers, Jan Okninski

Necessary and sufficient conditions are given for a prime Noetherian algebra K[S] of a submonoid S of a polycyclic-by-finite group G to be a maximal order. These conditions are ent…

Antisymmetric elements in group rings with an orientation morphism

O. Broche, E. Jespers, M. Ruiz

Let $R$ be a commutative ring, $G$ a group and $R G$ its group ring. Let $ϕ_{σ} : R G \to R G$ denote the involution defined by $ϕ_{σ} (\sum r_{g} g) = \sum r_{g} σ (g) g^{- 1}$ , where $σ:G\t…

Group identities on the units of algebraic algebras with applications to restricted enveloping algebras

Eric Jespers, David Riley, Salvatore Siciliano

An algebra is called a GI-algebra if its group of units satisfies a group identity. We provide positive support for the following two open problems. 1. Does every algebraic GI-alge…

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…
