Skew-rank of an oriented graph in terms of the rank and dimension of cycle space of its underlying graph

Yong Lu, Ligong Wang, Qiannan Zhou

Let $G^{σ}$ be an oriented graph and $S (G^{σ})$ be its skew-adjacency matrix, where $G$ is called the underlying graph of $G^{σ}$ . The skew-rank of $G^{σ}$ , denoted by $sr (G^{σ})$ , is the ra…

Hermitian-Randić matrix and Hermitian-Randić energy of mixed graphs

Yong Lu, Ligong Wang, Qiannan Zhou

Let $M$ be a mixed graph and $H (M)$ be its Hermitian-adjacency matrix. If we add every edge and arc in $M$ a Randić weight, then we can get a new weighted Hermitian-adjacency matri…
