On torsion subgroups in integral group rings of finite groups

Journal of Algebra, 2011
The authors investigate torsion subgroups of the normalized unit group \(V(\mathbb ZG)\) of the integral group ring \(\mathbb ZG\) of a finite group \(G\). For specific subgroups \(W\) they study the Gruenberg-Kegel graph \(\pi(W)\) of \(W\). Recall that the vertices of this graph are the primes dividing the order of a torsion element of the group \(W\)

Sur la torsion de la distribution ordinaire universelle attachée à un corps de nombres

, 2002
International audienceWe study the torsion subgroup of the universal ordinary distribution related to a general number field. We describe a way to control this subgroup.

Torsion Subgroups of Elliptic Curves over Quadratic Extensions

Journal of Number Theory, 1997
The paper considers the behaviour of the torsion subgroup of an elliptic curve over \(\mathbb{Q}\) under quadratic extension of the base field. The author proves the general result that for each elliptic curve \(E\) over \(\mathbb{Q}\), there are only finitely many quadratic extensions \(k\) of \(\mathbb{Q}\) such that the torsion subgroup of \(E(k ...
