Bounds for the positive or negative inertia index of a graph
Yi-Zheng Fan, Long Wang
Let be a graph and let be adjacency matrix of .The positive inertia index (respectively, the negative inertia index) of , denoted by (respectively, ),…
On the spectral radius of a class of non-odd-bipartite even uniform hypergraphs
Murad-ul-Islam Khan, Yi-Zheng Fan
In order to investigate the non-odd-bipartiteness of even uniform hypergraphs, starting from a simple graph , we construct a generalized power of , denoted by , whic…
The spectral radius of the square of graphs
Yi-Zheng Fan, Long Wang
The square of a connected graph is obtained from by adding an edge between every pair of vertices at distance . In this paper we give some upper or lower bounds for the…
Lower bounds for algebraic connectivity of graphs in terms of matching number or edge covering number
Jing Xu, Yi-Zheng Fan, Ying-Ying Tan
In this paper we characterize the unique graph whose algebraic connectivity is minimum among all connected graphs with given order and fixed matching number or edge covering number…
