Skew cyclic and skew constacyclic codes over the ring ??p + u1??p + ? + u2m??p

摘要

In this paper, we study skew cyclic and skew constacyclic codes over the ring ??p + u1??p + ? + u2m??p, where ui2 = u i and uiuj = 0, for i,j = 1,…, 2m and i≠j. We have introduced some new Gray maps and determined the relation between codes using the ??p-Gray images of skew constacyclic codes.
