Involutive Yang-Baxter Groups
Ferran Cedo, Eric Jespers, Angel del Rio
In 1992 Drinfeld posed the question of finding the set theoretic solutions of the Yang-Baxter equation. Recently, Gateva-Ivanova and Van den Bergh and Etingof, Schedler and Solovie…
The gap between the Schur group and the subgroup generated by cyclic cyclotomic algebras
Allen Herman, Gabriela Olteanu, Angel del Rio
Let be an abelian extension of the rationals. Let be the Schur group of and let be the subgroup of generated by classes containing cyclic cyclotomic a…
The Schur group of an abelian number field
Allen Herman, Gabriela Olteanu, Angel del Rio
We characterize the maximum -local index of a Schur algebra over an abelian number field in terms of global information determined by the field , for an arbitrary rat…
Group algebras of Kleinian type and groups of units
Gabriela Olteanu, Angel del Rio
The algebras of Kleinian type are finite dimensional semisimple rational algebras such that the group of units of an order in is commensurable with a direct product of Klei…
