The $γ$ -Signless Laplacian Adjacency Matrix of Mixed Graphs

Omar Alomari, Mohammad Abudayah, Manal Ghanem

The $α$ -Hermitian adjacency matrix $H_{α}$ of a mixed graph $X$ has been recently introduced. It is a generalization of the adjacency matrix of unoriented graphs. In this paper, we c…

Inverse of $α$ -Hermitian Adjacency Matrix of a Unicyclic Bipartite Graph

Mohammad Abudayah, Omar Alomari, Omar AbuGhneim

Let $X$ be bipartite mixed graph and for a unit complex number $α$ , $H_{α}$ be its $α$ -hermitian adjacency matrix. If $X$ has a unique perfect matching, then $H_{α}$ has a hermitian in…

Incidence matrices and line graphs of mixed graphs

Mohammad Abudayah, Omar Alomari, Torsten Sander

In the theory of line graphs of undirected graphs there exists an important theorem linking the incidence matrix of the root graph to the adjacency matrix of its line graph. For di…
