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…
