Z_q(Z_q+uZ_q)-Linear Skew Constacyclic Codes
In this paper, we study skew constacyclic codes over the ring where , for a prime and We give the definition of these codes as subsets of the ring . Some structural properties of the skew polynomial ring are discussed, where is an automorphism of We describe the generator polynomials of skew constacyclic codes over also we determine their minimal spanning sets and their sizes. Further, by using the Gray images of skew constacyclic codes over we obtained some new linear codes over . Finally, we have generalized these codes to double skew constacyclic codes over
