WebOct 30, 2024 · The main result of this work is the finding that the (adjacency) graph energy of any graph can be obtained as a weighted sum of even powers of the adjacency matrix. First, we observe that (5) E G = tr A , where A = V Λ V T stands for the absolute value matrix function of A. Then, we have the following result. Theorem 1 WebMar 20, 2024 · We obtain a relationship between the Laplacian energy and the distance Laplacian energy for graphs with diameter 2. We obtain lower bounds for the distance Laplacian energy DLE ( G) in terms of the order n, the Wiener index W ( G ), the independence number, the vertex connectivity number and other given parameters.

Web1. Draw a potential energy graph for an endothermic and exothermic reaction. What can be said about how the energy of the products compares to the energy of the reactants in each graph? On endothermic graphs, the products will always come out to be higher than the reactants, on exothermic graphs, the products will have a lower outcome than the … WebThe chart below shows U.S. energy sources, their major uses, and their percentage shares of total U.S. energy consumption in 2024.

Laplacian Energy of a Graph with Self-Loops
WebThe derived graph of a simple graph G, denoted by G\ is a graph having same vertex set as G, in which two vertices are adjacent if and only if their distance in G is two. In this paper, we establish an upper and lower bounds for color energy of a graph and obtain color energy of derived graphs of some families of graphs.", WebFew properties on distance eigenvalues and bounds for distance energy of connected partial complement of a graph are achieved. Further distance energy of connected partial complement of some families of graphs are computed. AB - The partial complement of a graph G with respect to a set S is the graph obtained from G by removing the edges of ...
