Galois LCD Codes Over Fq + uFq + vFq + uvFq
share
In <cit.>, Wu and Shi studied l-Galois LCD codes over finite chain ring β=π½_q+uπ½_q, where u^2=0 and q=p^e for some prime p and positive integer e. In this work, we extend the results to the finite non chain ring β =π½_q+uπ½_q+vπ½_q+uvπ½_q, where u^2=u,v^2=v and uv=vu. We define a correspondence between l-Galois dual of linear codes over β and l-Galois dual of its component codes over π½_q . Further, we construct Euclidean LCD and l-Galois LCD codes from linear code over β. This consequently leads us to prove that any linear code over β is equivalent to Euclidean (q>3) and l-Galois LCD (0<l<e, and p^e-l+1| p^e-1) code over β . Finally, we investigate MDS codes over β .
