某类恰含两个交点的本原不可幂定号有向图的第一类广义基

The First Type Generalized Base of a Primitive Non-powerful Signed Digraph with Two Common Points

利用图论的相关方法,讨论了一类恰含有两个交点的n阶本原不可幂定号有向图,通过分析图形特点,综合运用SSSD途径对、Frobenius指数和异圈对的相关理论,进而得出这类本原不可幂定号有向图的第一类广义基,即Local基。

By using graph theory, the primitive non-powerful signed digraph with two common points was discussed. The local base of this special primitive non-powerful signed digraph was obtained by analyzing the characteristics of SSSD walks, Frobenius and distinguished cycle pair.
