摘要：
Self-dual cyclic codes over rings and their generalizations have become of interest due to their rich algebraic structures and wide applications. Cyclic and self-dual cyclic codes over the ring have been quite well studied, where p is a prime, k is a positive integer, and u2=0. We focus on negacyclic codes over , where p is an odd prime and k is a positive integer. An alternative and explicit algebraic characterization of negacyclic codes of length ps over is presented. Based on this result, representation and enumeration of self-dual negacyclic codes of length ps over are given under both the Euclidean and Hermitian inner products.
