On the Distribution of Vertex Energy of Connected Non-Regular Non-Bipartite Integral Graphs with Maximum Vertex Degree Four

Scientific Annals of Computer Science
The energy of a vertex in a graph plays a very important role in terms of its contribution to the total energy of a graph, a significant graph invariant in the field of chemical graph theory.

Some new relations between Sombor index and graph energy

Examples and Counterexamples
Let G be a graph with {v1,…,vn} being vertices and di being the corresponding vertex degrees. The Sombor index of G is denoted by SO(G) and is defined by SO(G)=∑i∼jdi2+dj2 where i∼j means there exists an edge between the vertices vi and vj.

Seidel Switching and Graph Energy [PDF]

SSRN Electronic Journal, 2012
The energy of a graph Γ is the sum of the absolute values of the eigenvalues of the adjacency matrix of Γ. Seidel switching is an operation on the edge set of Γ. In some special cases Seidel switching does not change the spectrum, and therefore the energy. Here we investigate when Seidel switching changes the spectrum, but not the energy. We present an

Color energy of a graph

, 2013
In this paper, we introduce the concept of color energy of a graph, E C(G) and compute the color energy EX(G) of few families of graphs with minimum number of colors. It depends on the underlying graph and colors on its vertices.

Modeling of a Biomass-Based Energy Production Case Study Using Flexible Inputs with the P-Graph Framework

In this work, a modeling technique utilizing the P-Graph framework was used for a case study involving biomass-based local energy production. In recent years, distributed energy systems gained attention. These systems aim to satisfy energy supply demands,

Skew-spectra and skew energy of various products of graphs [PDF]

Transactions on Combinatorics, 2015
Given a graph $G$, let $G^sigma$ be an oriented graph of $G$ with the orientation $sigma$ and skew-adjacency matrix $S(G^sigma)$. Then the spectrum of $S(G^sigma)$ consisting of all the eigenvalues of $S(G^sigma)$ is called the skew-spectrum of $G ...

Applications on color (distance) signless laplacian energy of annihilator monic prime graph of commutative rings

Ain Shams Engineering Journal
In this study, we define the structure formation of the annihilator monic prime graph of commutative rings, whose distinct vertices X and J satisfies a condition annXJ≠annX⋃ann(J), graph is denoted by AMPG(Zn[x]/〈fx〉).
