1.
In this paper, the U-track and strictly directed bipartite graph are defined.
对图的邻接矩阵赋予U-轨道的定义和严格有向二部图的定义,利用U-轨道的定义和Hamilton路的定义论证了严格有向图含有向Hamilton路的充要条件和严格有向二部图为Hamilton图的充分条件。

A sufficient condition of strictly directed bipartite graph with directed Hamiltonian path is given, that is, suppose that D is a strictly directed Bipartite graph on n vertices, (in it V(D)=(X,Y),‖X｜-｜Y‖≤1), if two arbitraily nonadjacent vertices x,y in V(D) have d(x)+d(y)≥2n-4, then D has directed Hamiltonian path.
给出了严格有向二部图含有向Hamilton路的一个充分条件,即:设D是n阶严格有向二部图(其中V(D)=(X,Y),‖X|-|Y‖≤1),若V(D)中任两个不相邻的顶点x,y,都有d(x)+d(y)≥2n-4,则D含有向Hamilton路。
3) strictly unilateral digraph
严格单侧有向图
4) strictly weak digraph
严格弱有向图
5) strictly positive vector
严格;正向量
