On determinants of tournaments and
Jing Zeng, Lihua You
Let be a tournament with vertices . The skew-adjacency matrix of is the zero-diagonal matrix in which if…
The maximum spectral radius of graphs of given size with forbidden subgraph
Xiaona Fang, Lihua You
Let be a graph of size and be the spectral radius of its adjacency matrix. A graph is said to be -free if it does not contain a subgraph isomorphic to . In thi…
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…
