Additive codes over Galois rings
收藏 引用
FINITE FIELDS AND THEIR APPLICATIONS 2019年 56卷 332-350页
作者: Mahmoudi, Saadoun Samei, Karim Bu Ali Sina Univ Dept Math Hamadan Iran
Let S = GR(p(e), m) be a Galois ring of characteristic p(e) and cardinality p(em). An additive code over S of length n is a subgroup of S-n under addition. In this paper, we study additive codes over S. We introduce a... 详细信息

In this article, we study negacyclic self-dual codes of length n over a finite chain ring R when the characteristic p of the residue field (R) over bar and the length n are relatively prime. We give necessary and suff... 详细信息

DISCRETE MATHEMATICS 2020年 第3期343卷 111771-000页
作者: Han, Nayoung Kim, Bohyun Kim, Boran Lee, Yoonjin Ewha Womans Univ Dept Math Seoul 03760 South Korea Sungkyunkwan Univ Dept Math Suwon 16419 South Korea
We study alpha-constacyclic codes over the Frobenius non-chain ring R := Z(4)[u]/ for any unit alpha of R. We obtain new mdr cyclic codes over Z(4) using a close connection between alpha-constacyclic codes over R and ... 详细信息
