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…

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…
