Iota energy orderings of bicyclic signed digraphs

The concept of energy of a signed digraph is extended to iota energy of a signed digraph‎. ‎The energy of a signed digraph $S$ is defined by $E(S)=\sum_{k=1}^n|{Re}(z_k)|$‎, ‎where ${Re}(z_k)$ is the real part of eigenvalue $z_k$ and $z_k$ is the eigenvalue of the adjacency matrix of $S$ with $n$ ve...
