Özet

In this work, we study codes generated by elements in the skew group matrix ring Mk(R) (Formula Presented), where R is a finite commutative Frobenius ring, G is an arbitrary finite group, and (Formula Presented) is a group homomorphism from G to Aut(Mk(R)). We then determine all possible group homomorphisms (Formula Presented): G → Aut(M2(F2)), for the cases where G is a cyclic group and a dihedral group. Finally, by using skew generator matrices we provide examples of binary self-dual codes and also binary linear optimal codes.
