非简单有向图情形下Adm猜想的证明

The Proof of Adáms Conjecture in the Case of Non Simple Digraph

在非简单有向图情形下证明了Ａｄáｍ关于“若Ｄ是包含有向圈的有向图，则存在某弧，把它反向之后将减少Ｄ中有向圈的数目”

In this paper,the Adáms conjecture,that is 'If D is a digraph including directed cycles,then there exists an arc,the numbers of directed cycle in D will be decreased when the arc changes to opposite direction.',has been proved in the case of simple digraph. [
