Orders of units in integral group rings and blocks of defect

Mauricio Caicedo, Leo Margolis

We show that if the Sylow -subgroup of a finite group is of order , then the normalized unit group of the integral group ring of contains a normalized unit of order $…

On the Zassenhaus Conjecture for certain cyclic-by-nilpotent groups

Mauricio Caicedo, Ángel del Río

Hans Zassenhaus conjectured that every torsion unit of the integral group ring of a finite group is conjugate within the rational group algebra to an element of the form $\pm g…

Global and local properties of finite groups with only finitely many central units in their integral group ring

Andreas Bächle, Mauricio Caicedo, Eric Jespers +1

The aim of this article is to explore global and local properties of finite groups whose integral group rings have only trivial central units, so-called cut groups. For such a grou…

On the Prime Graph Question for Almost Simple Groups with an Alternating Socle

Andreas Bächle, Mauricio Caicedo

Let be an almost simple group with socle , the alternating group of degree . We prove that there is a unit of order in the integral group ring of if and only i…

A classification of exceptional components in group algebras over abelian number fields

Andreas Bächle, Mauricio Caicedo, Inneke Van Gelder

When considering the unit group of ( the ring of integers of an abelian number field and a finite group ) certain components in the Wedderbu…

Zassenhaus conjecture for cyclic-by-abelian groups

Mauricio Caicedo, Leo Margolis, Ángel del Río

Zassenhaus Conjecture for torsion units states that every augmentation one torsion unit of the integral group ring of a finite group G is conjugate to an element of G in the units…
