ABSTRACT We identify all small groups of order up to 288 in the GAP Library for which the Zassenhaus conjecture on rational conjugacy of units of finite order in the integral group ring cannot be established by an existing method. The groups must first survive all theoretical sieves and all known restrictions on partial augmentations (the HeLP+ method). Then two new computational methods for verifying the Zassenhaus conjecture are applied to the unresolved cases, which we call the quotient… Expand
On the First Zassenhaus Conjecture and Direct Products
Abstract In this paper we study the behavior of the first Zassenhaus conjecture (ZC1) under direct products, as well as the General Bovdi Problem (Gen-BP), which turns out to be a slightly weakerExpand
Partial augmentations power property: A Zassenhaus Conjecture related problem
Zassenhaus conjectured that any unit of finite order in the integral group ring $\mathbb{Z}G$ of a finite group $G$ is conjugate in the rational group algebra of $G$ to an element in $\pm G$. WeExpand
From examples to methods: two cases from the study of units in integral group rings
In this article, we review the proofs of the first Zassenhaus Conjecture on conjugacy of torsion units in integral group rings for the alternating groups of degree 5 and 6, by Luthar-Passi andExpand
Finite Subgroups of Group Rings: A survey
In the 1940's Graham Higman initiated the study of finite subgroups of the unit group of an integral group ring. Since then many fascinating aspects of this structure have been discovered. MajorExpand
Algorithmic Aspects of Units in Group Rings
We describe the main questions connected to torsion subgroups in the unit group of integral group rings of finite groups and algorithmic methods to attack these questions. We then prove theExpand
On Torsion Units in Integral Group Ring of A Dicyclic Group
Let G become an any group. We recall that any two elements of integral group ring ZG are rational conjugate provided that they are conjugate in terms of units in QG. Zassenhaus introduced as aExpand
A counterexample to the first Zassenhaus conjecture
Hans J. Zassenhaus conjectured that for any unit $u$ of finite order in the integral group ring of a finite group $G$ there exists a unit $a$ in the rational group algebra of $G$ such thatExpand

Simply reducible groups are closely related to the eigenvalue problems in quantum theory and molecular symmetry in chemistry. Classification of simply reducible groups is still an open problem whichExpand

Revisiting the Zassenhaus conjecture on torsion units for the integral group rings of small groups
In recent years several new restrictions on integral partial augmentations for torsion units of ℤG$\mathbb {Z} G$ have been introduced, which have improved the effectiveness of the Luthar–PassiExpand
Rational Conjugacy of Torsion Units in Integral Group Rings of Non-Solvable Groups
Abstract We introduce a new method to study rational conjugacy of torsion units in integral group rings using integral and modular representation theory. Employing this new method, we verify theExpand
Zassenhaus conjecture for central extensions of S 5
Abstract We confirm a conjecture of Zassenhaus about rational conjugacy of torsion units in integral group rings for a covering group of the symmetric group S 5 and for the general linear group GL(2,Expand
Zassenhaus Conjecture for cyclic-by-abelian groups
The Zassenhaus Conjecture for torsion units has been proved for nilpotent groups, metacyclic groups and some other families of groups, and the conjecture for cyclic-by-abelian groups is proved. Expand
On the Torsion Units of Some Integral Group Rings
It is shown that any torsion unit of the integral group ring ZG of a flnite group G is rationally conjugate to a trivial unit if G = P o A with P a normal Sylow p-subgroup of G and A an abelian p 0Expand
For a torsion unit u of the integral group ring ZG of a nite group G, and a prime p which does not divide the order of u (but the order of G), a relation between the partial augmentations of u on theExpand

Abstract It is shown that any torsion unit of the integral group ring $\mathbb{Z}G$ of a finite group $G$ is rationally conjugate to an element of $\pm G$ if $G=XA$ with $A$ a cyclic normal subgroupExpand
Torsion units in integral group rings.
More precisely, we are interested in classifying the group homomorphisms α:Γ -> t/!(Z/7) where 77, Γ are both finite groups. Two such homomorphisms α', α are called Z-equivalent if a unit u of Z/7Expand
