摘要 本文研究有限链环上一类λ-常循环码.利用x^n-1在R_a[x]上可唯一分解为两两互素的首一基本不可约多项式乘积,刻画了R_a中长为p^sn的所有λ-常循环码,推广了开晓山等人在文献[4]中的结果. We study a class of A-constacyclic codes.By using the unique factorizations of x^n- 1 into a product of monic basic irreducible pairwise coprime polynomials over Ra[x],we characterize the structure of A-constacyclic codes of length p^sn over Fp^m[u]/〈u^a〉,which generalizes the result of[4].
