Generalized Bases of a Class of Primitive Non-powerful Signed Nearly Reducible Digraphs with Two Cycles

研究了一类恰含两个圈的本原不可幂定号有向图,通过分析图形特点,综合利用SSSD途径对和Frobenius指数的特性推导出这类图的广义基.

The generalized bases of a class of primitive non-powerful nearly reducible signed digraphs with two cycles are discussed. With the analysis of this digragh and the characteristics of SSSD walks and Frobenius, the generalized bases of this class digraphs are concluded.
