WebThe graph (formula presented) thus obtained is called the k (i)−complement of graph G with respect to the partition P. Energy of a graph G is the sum of absolute eigenvalues of G. In this paper, we study energy of generalized complements of some families of graph. An effort is made to throw some light on showing variation in energy due to ... 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

WebTotal energy consumption by end-use sectors in this chart exclude electrical system . energy losses and differ from the totals published in MER Table 2.1, which allocates electrical system energy losses proportionally to the amount of electricity retail sales to each end-use sector. Transportation WebThe purpose of this paper is to extend the concept of Laplacian energy from simple graph to a graph with self-loops. Let G be a simple graph of order n, size m and GS is the graph obtained from G by adding σ self-loops. We define Laplacian energy of GS as (Formula Presented) are eigenvalues of the Laplacian matrix of Gs. WebIn this paper, we introduce new kind of graph energy, the minimum vv-dominating Laplacian energy of a graph denoting it as LEvv(G). It depends both on the underlying graph of G and the particular minimum vv-dominating set of G. Upper and lower bounds for LEvv(G) are established and we also obtain the minimum vv-dominating Laplacian … date and time sync
