LCD and self-orthogonal twisted group codes over finite commutative chain rings
Samir Assuena, André Luiz Martins Pereira
In this paper, we shall study k-Galois LCD constacyclic group codes over finite commutative chain rings with identity. In particular, we shall characterize Galois LCD constacyclic…

Good codes from twisted group algebras
Samir Assuena
In this paper, we shall give an explicit proof that constacyclic codes over finite commutative rings can be realized as ideals in some twisted group rings. Also, we shall study iso…

Good Codes From Dihedral Groups
Samir Assuena, César Polcino Milies
We give a simple construction of codes from left ideals in group algebras of certain dihedral groups and give an example to show that they can produce codes with weights equal to t…
