Three results on twisted codes and skew twisted codes
Alvaro Otero Sanchez
In this paper we solve an open question formulated in the original paper of twisted skew group codes regarding when a twisted skew group code is checkable. Also, we prove that all…

Derivation over twisted group ring and its applications
Alvaro Otero Sanchez
This paper classifies the derivations of twisted group algebras in terms of the generators and defining relations of the group. In particular, we generalize some know results over…

The homology of the groupoid of the self-similar dihedral group
Eduard Ortega, Alvaro Sanchez
We give an example of a locally compact effective Hausdorff, minimal ample groupoid such that its rational homology differs from the -theory of its reduced groupoid -algebr…
