Energy of a digraph with respect to a VDB topological index
Let DD be a digraph with vertex set VV and arc set EE. For a vertex uu, the out-degree and in-degree of uu are denoted by du+{d}_{u}^{+} and du−{d}_{u}^{-}, respectively. A vertex-degree-based (VDB) topological index φ\varphi is defined for DD as φ(D)=12∑uv∈Eφdu+,dv−,\varphi (D)=\frac{1}{2}\sum _{u...
