Spectrum of a class of matrices and its applications
Lihua You, Man Yang, JInxi Li +1
In this paper, we give the spectrum of a matrix by using the quotient matrix, then we apply this result to various matrices associated to a graph and a digraph, including adjacency…
A Sharp upper bound for the spectral radius of a nonnegative matrix and applications
Lihua You, Yujie Shu, Xiao-Dong Zhang
In this paper, we obtain a sharp upper bound for the spectral radius of a nonnegative matrix. This result is used to present upper bounds for the adjacency spectral radius, the Lap…
Distance and distance signless Laplacian spread of connected graphs
Lihua You, Liyong Ren, Guanglong Yu
For a connected graph on vertices, recall that the distance signless Laplacian matrix of is defined to be , where …
A characterization of arithmetic functions satisfying
Lihua You, Yafei Chen, Pingzhi Yuan
In this paper, we mainly discuss the characterization of a class of arithmetic functions such that . We obt…
On some properties of three different types of triangular blocked tensors
Jiayu Shao, Lihua You
We define three types of upper (and lower) triangular blocked tensors, which are all generalizations of the triangular blocked matrices. We study some basic properties and characte…
