Group algebras whose units satisfy a Laurent Polynomial Identity

Osnel Broche, Jairo Z. Gonçalves, Ángel del Río

Let $K G$ be the group algebra of a torsion group $G$ over a field $K$ . We show that if the units of $K G$ satisfy a Laurent polynomial identity which is not satisfied by the units o…

An algorithm to construct candidates to counterexamples to the Zassenhaus Conjecture

Leo Margolis, Ángel del Río

Let $G$ be a finite group, $N$ a nilpotent normal subgroup of $G$ and let $V (Z G, N)$ denote the group formed by the units of the integral group ring $\mathbb{\Z…

Cliff-Weiss Inequalities and the Zassenhaus Conjecture

Leo Margolis, Ángel del Río

Let $N$ be a nilpotent normal subgroup of the finite group $G$ . Assume that $u$ is a unit of finite order in the integral group ring $Z G$ of $G$ which maps to the identit…
