| Abstract: |
| In this paper, we investigate skew cyclic and LCD codes over the ring R=Fq+uFq+vFq(u2=u,v2=v,uv=vu=0), where q is a prime power. Using some decompositions of linear codes and their duals over ring R, we obtain the generator polynomials of skew cyclic and their dual codes over R. Finally, we address the relationship of LCD codes between R and Fq. By means of the Gray map from R to Fq3, we obtain that Gray images of LCD codes over R are LCD codes over Fq. |
