The set of singular values of a digraph with respect to a vertex-degree based topological index is the set of all singular values of its general adjacency matrix. The spectral norm is the largest singular value and the energy the sum of the singular

We assume that D is a directed graph with vertex set V(D)={v1,…vn} and arc set E(D). A VDB topological index φ of D is defined asφ(D)=12∑uv∈E(D)φdu+,dv−, where du+ and dv− denote the outdegree and indegree of vertices u and v, respective

Let D be a digraph with set of arcs A. The Sombor index of D is defined asSO(D)=12∑uv∈A(du+)2+(dv−)2,where du+ and dv− are the out-degree and in-degree of the vertices u and v of D. When D is a graph, we recover the Sombor index of graphs, a

A vertex-degree-based (VDB, for short) topological index φ induced by the numbers φij was recently defined for a digraph D, as φD=12∑uvφdu+dv−, where du+ denotes the out-degree of the vertex u,dv− denotes the in-degree of the vertex v, and

Let D D be a digraph with vertex set V V and arc set E E . For a vertex u u , the out-degree and in-degree of u u are denoted by d u + {d}_{u}^{+} and d u − {d}_{u}^{-} , respectively. A vertex-degree-based (VDB) topological index φ \varphi is def

Let D n be the set of digraphs with n non-isolated vertices. Let D ∈ D n and denote by d u + and d u − the outer degree and inner degree, respectively, of the vertex u of D . We define the vertex-degree-based (VDB, for short) topological index φ
