The generalized distance matrix of digraphs

Weige Xi, Wasin So, Ligong Wang

Let $D (G)$ and $D^{Q} (G) = D ia g (T r) + D (G)$ be the distance matrix and distance signless Laplacian matrix of a simple strongly connected digraph $G$ , respectively, where $Diag(Tr)=\te…

Merging the A- and Q-spectral theories for digraphs

Weige Xi, Wasin So, Ligong Wang

Let $G$ be a digraph and $A (G)$ be the adjacency matrix of $G$ . Let $D (G)$ be the diagonal matrix with outdegrees of vertices of $G$ . For any real $α \in [0, 1]$ , Liu et al. \cite{LWC…
