摘要
主要解决了M.Satyanarayana在文[1]中提出的一个问题:证明若一个码X≠满足A+X XA+,则X是一致码.同时给出了一个右完全码X满足A*X XA*的一些充要条件.
In this paper, we prove that if X≠ is a code over an alphabet A satisfying the condition A^+XXA^+, thenis X a uniform code which completely solved an open problem in~\{\\}. We also find some sufficient and necessary conditions on a right complete code satisfying the condition A~*XXA~*.
