On the inertia index of a Mixed Graph in Terms of the Matching Number
收藏 引用
Acta Mathematicae Applicatae Sinica 2023年 第3期39卷 591-604页
作者: Sheng-jie HE Rong-Xia HAO Ai-mei YU School of Mathematics and Statistics Beijing Jiaotong UniversityBeijing 100044China
A mixed graph G^(-) is obtained by orienting some edges of G, where G is the underlying graph of G^(-) . The positive inertia index, denoted by p~+( G), and the negative inertia index, denoted by n~-(G^(-) ), of a mix... 详细信息
