Center node: "on skew cyclic codes over fq vfq v 2 fq"
  Abstract: In the present paper, we study skew cyclic codes over the ring Fq+vFq+v 2 Fq, where v 3 = v, q = p m and p is an odd prime. We investigate the structural properties of skew cyclic codes over Fq + vFq + v 2 Fq using decomposition method. By defining a Gray map from Fq + vFq + v 2 Fq to F 3 q , it has been proved that the Gray image of a skew cyclic code of length n over Fq + vFq + v 2 Fq is a skew 3-quasi cyclic code of length 3n over Fq. Further, it is shown that the skew cyclic codes over Fq + vFq + v 2 Fq are principally generated. Finally, the idempotent generators of skew cyclic codes over Fq + vFq + v 2 Fq are also obtained.
