摘要

有向图是每条边都有一个方向的图。线性有向路径是所有边方向相同的路径。如果线性简单图允许满足一定条件的0 - 1标记，则称为有向诚恳图。本文研究了有向路径的亲切性及其二次幂。类似的研究也在进行中。我们表明了这一点，并受到亲切的指导。给出了连接可定向的充分条件。

Some Results on Cordial Digraphs

A digraph is a graph in which each edge has an orientation. A linear directed path, , is a path whose all edges have the same orientation. A linear simple graph is called directed cordial if it admits 0 - 1 labeling that satisfies certain condition. In this paper, we study the cordiality of directed paths and their second power . Similar studies are done for and the join . We show that , and are directed cordial. Sufficient conditions are given to the join to be directed cordial.
