On the Modular Isomorphism Problem for 2-generated groups with cyclic derived subgroup

Diego García-Lucas, Ángel del Río

We continue the analysis of the Modular Isomorphism Problem for $2$ -generated $p$ -groups with cyclic derived subgroup, $p > 2$ , started in [D. García-Lucas, Á. del Río, and M. Stanoj…

The isomorphism problem for rational group algebras of finite metacyclic groups

Ángel del Río, Àngel García-Blázquez

We prove that if two finite metacyclic groups have isomorphic rational group algebras, then they are isomorphic. This contributes to understand where is the line separating positiv…

Gruenberg-Kegel graphs: cut groups, rational groups and the Prime Graph Question

Andreas Bächle, Ann Kiefer, Sugandha Maheshwary +1

The Gruenberg-Kegel graph of a group is the undirected graph whose vertices are those primes which occur as the order of an element of the group, and distinct vertices $p$ , $q$ are…

On the Congruence Subgroup Problem for integral group rings

Mauricio Caicedo, Ángel del Río

Let $G$ be a finite group, $Z G$ the integral group ring of $G$ and $\U(\Z G)$ the group of units of $Z G$ . The Congruence Subgroup Problem for $\U(\Z G)$ is the problem of decid…
