Bounds for Incidence Energy of Some Graphs [PDF]
Journal of Applied Mathematics, 2013 Let G be a simple graph. The incidence energy (IE for short) of G is defined as the sum of the singular values of the incidence matrix. In this paper, a new upper bound for IE of graphs in terms of the maximum degree is given. Meanwhile, bounds for IE of

On the Diameter and Incidence Energy of Iterated Total Graphs [PDF]
Symmetry, 2018 The total graph of G, T(G) is the graph whose vertex set is the union of the sets of vertices and edges of G, where two vertices are adjacent if and only if they stand for either incident or adjacent elements in G. For k≥2, the k-th iterated total graph of G, Tk(G), is defined recursively as Tk(G)=T(Tk−1(G)), where T1(G)=T(G) and T0(G)=G.

On the maximum ABC index of bipartite graphs without pendent vertices
Open Chemistry, 2020 For a simple graph G, the atom–bond connectivity index (ABC) of G is defined as ABC(G) = ∑uv∈ E(G)d(u)+d(v)−2d(u)d(v), $\sum_{uv\in{}E(G)} \sqrt{\frac{d(u)+d(v)-2}{d(u)d(v)}},$where d(v) denotes the degree of vertex v of G.
