摘要
设X~*是字母表X上的自由幺半群,以X~*为顶点集构造一个语言图Г(X~*),引入语言图Г(X~*)的横截集的概念,给出了极大前缀码的一些刻划.
Let X~* be the free monoid on the alphabet set X.The concept of a transversal of the language diagramΓ(X~*) is introduced by constructing a language diagramΓ(X~*) with X~* as the node set and some characterizations of maximal prefix codes are given.
