On energy ordering of vertex-disjoint bicyclic sidigraphs
The energy and iota energy of signed digraphs are respectively defined by $E(S)=$ $\sum_{k=1}^n|{\rm Re}(\rho_k)|$ and $E_c(S)=\sum_{k=1}^n|{\rm Im }(\rho_k)|$, where $\rho_1, \dots,\rho_n$ are eigenvalues of $S$, and ${\rm Re}(\rho_k)$ and ${\rm Im}(\rho_k)$ are respectively real and imaginary valu...
