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

Nullity of Hermitian-Adjacency Matrices of mixed graphs
收藏 引用
Journal of Mathematical Research with Applications 2018年 第1期38卷 23-33页
作者: Fenglei TIAN Dein WONG School of Mathematics China University of Mining and Technology
A mixed graph means a graph containing both oriented edges and undirected edges. The nullity of the Hermitian-adjacency matrix of a mixed graph G, denoted by ηH(G),is referred to as the multiplicity of the eigenvalue... 详细信息
