Abstract

A directed graph is semi-transitive if and only if it is acyclic and for any directed path $u_1\rightarrow u_2\rightarrow \cdots \rightarrow u_t$, $t \geq 2$, either there is no edge from $u_1$ to $u_t$ or all edges $u_i\rightarrow u_j$ exist for $1 \leq i

由态射生成的有向分裂图的半可及性
一个有向图是半传递的当且仅当它是非循环的,并且对于任何有向路径$u_1\rightarrow u_2\rightarrow \cdots \rightarrow u_t$, $t \geq 2$,要么没有从$u_1$到$u_t$的边,要么$1 \leq i
