The row left rank of quaternion unit gain graphs in terms of pendant vertices

Yong Lu, Qi Shen

Let $G = (G, U (Q), I ¨ )$ be a quaternion unit gain graph (or $U (Q)$ -gain graph), where $G$ is the underlying graph of $G$ , $U(\mathbb{Q})=\{q\i…

The row left rank of a quaternion unit gain graph in terms of maximum degree

Yong Lu, Qi Shen

Let $I^¦ = (G, U (Q), I ¨ )$ be a quaternion unit gain graph (or $U (Q)$ -gain graph) of order $n$ , $A (I^¦)$ be the adjacency matrix of $I^¦$ and $r (I^¦)$ be the row left rank…

The left row rank of quaternion unit gain graphs in terms of girth

Yong Lu, Qi Shen, JiaXu Zhong

Let $I^¦ = (G, U (Q), I ¨ )$ be a quaternion unit gain graph (or $U (Q)$ -gain graph). The adjacency matrix of $I^¦$ is denoted by $A (I^¦)$ and the left row rank of $I^¦$ is d…
