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…

New result and some open problems on the primitive degree of nonnegative tensors

Pingzhi Yuan, Zilong He, Lihua You

In this paper, we show that the exponent set of nonnegative primitive tensors with order m(\geq 3) and dimension n is {1,2,\ldots, (n-1)^2+1}; and propose some open problems for fu…

Some remarks on P, P_0, B and B_0 tensors

Pingzhi Yuan, Lihua You

Recently, Song and Qi extended the concept of P, P_0 and B matrices to P, P_0, B and B_0 tensors, obtained some properties about these tensors, and proposed many questions for furt…
