In this paper we consider completely decomposable torsion-free groups and we determine the subgroups which are ideals in every ring over such groups.

Classification of self-dual torsion-free LCA groups

Fundamenta Mathematicae

Similarity:

In this paper we seek to describe the structure of self-dual torsion-free LCA groups. We first present a proof of the structure theorem of self-dual torsion-free metric LCA groups. Then we generalize the structure theorem to a larger class of self-dual torsion-free LCA groups. We also give a characterization of torsion-free divisible LCA groups. Consequently, a complete classification of self-dual divisible LCA groups is obtained; and any self-dual torsion-free LCA group can be regarded...

Action of the Grothendieck-Teichmüller group on torsion elements of full Teichmüller modular groups in genus zero

Journal de Théorie des Nombres de Bordeaux

Similarity:

In this paper we establish the action of the Grothendieck-Teichmüller group $\hat{G T}$ on the prime order torsion elements of the profinite fundamental group $π_{1}^{g e o m} (ℳ_{0, [n]})$ . As an intermediate result, we prove that the conjugacy classes of prime order torsion of ${\hat{π}}_{1} (ℳ_{0, [n]})$ are exactly the prime order ones of the $π_{1} (ℳ_{0, [n]})$ .
