Some results of strongly primitive tensors

Lihua You, Yafei Chen, Pingzhi Yuan

In this paper, we show that an order $m$ dimension 2 tensor is primitive if and only if its majorization matrix is primitive, and then we obtain the characterization of order $m$ d…

Distance and distance signless Laplacian spread of connected graphs

Lihua You, Liyong Ren, Guanglong Yu

For a connected graph $G$ on $n$ vertices, recall that the distance signless Laplacian matrix of $G$ is defined to be $Q (G) = T r (G) + D (G)$ , where $D (G)$ …

A characterization of arithmetic functions satisfying $f (u^{2} + k v^{2}) = f^{2} (u) + k f^{2} (v)$

Lihua You, Yafei Chen, Pingzhi Yuan

In this paper, we mainly discuss the characterization of a class of arithmetic functions $f : N \to C$ such that $f (u^{2} + k v^{2}) = f^{2} (u) + k f^{2} (v)$ $(k, u, v \in N)$ . 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…
