%X 本文研究有限链环上一类λ-常循环码.利用xn-1在Ra[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Ra中长为psn的所有λ-常循环码,推广了开晓山等人在文献[4]中的结果.<br>We study a class of λ-constacyclic codes. By using the unique factorizations of xn-1 into a product of monic basic irreducible pairwise coprime polynomials over Ra[x], we characterize the structure of λ-constacyclic codes of length psn over Fpm[u]/<ua>, which generalizes the result of[4]
