On the Incidence Energy of Some Toroidal Lattices [PDF]

open access: yesAbstract and Applied Analysis, 2014
The incidence energy IE(G), defined as the sum of the singular values of the incidence matrix of G, is a much studied quantity with well known applications in chemical physics.

Bounds for Incidence Energy of Some Graphs [PDF]

open access: yesJournal 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

The Non-Linear Effects of Energy Efficiency Gains on the Incidence of Energy Poverty [PDF]

open access: yesSustainability, 2021
Energy poverty is defined as insufficient access to modern energy resources which are relatively cleaner than the traditionally utilized ones. In this regard, the incidence of energy poverty is particularly higher in the cases of the developing countries across the globe. Accordingly, the chronic energy poverty issues in the developing countries within

On Incidence Energy

open access: yes, 2014
The incidence energy of a graph is defined as the sum of singular values of its incidence matrix. In this paper, we establish some new bounds on the incidence energy of connected graphs.

Randi'c incidence energy of graphs [PDF]

open access: yesTransactions on Combinatorics, 2014
Let $G$ be a simple graph with vertex set $V(G) = {v_1, v_2,ldots , v_n}$ and edge set $E(G) = {e_1, e_2,ldots , e_m}$. Similar to the Randi'c matrix, here we introduce the Randi'c incidence matrix of a graph $G$, denoted by $I_R(G)$, which is defined

On the Diameter and Incidence Energy of Iterated Total Graphs [PDF]

open access: yesSymmetry, 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 oriented incidence energy and decomposable graphs [PDF]

open access: yesFilomat, 2009
Let G be a simple graph with n vertices and m edges. Let edges of G be given an arbitrary orientation, and let Q be the vertex-edge incidence matrix of such oriented graph. The oriented incidence energy of G is then the sum of singular values of Q.
