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…
On the exponent set of nonnegative primitive tensors
Zilong He, Pingzhi Yuan, Lihua You
In this paper, we present a necessary and sufficient condition for a nonnegative tensor to be a primitive one, show that the exponent set of nonnegative primitive tensors with orde…
The Minimal Total Irregularity of Graphs
Yingxue Zhu, Lihua You, Jieshan Yang
In \cite{2012a}, Abdo and Dimitov defined the total irregularity of a graph as \hskip3.3cm \noindent…
Spectral radius and signless Laplacian spectral radius of strongly connected digraphs
Wenxi Hong, Lihua You
Let D be a strongly connected digraph and A(D) be the adjacency matrix of D. Let diag(D) be the diagonal matrix with outdegrees of the vertices of D and Q(D) = diag(D) + A(D) be th…
