图G的关联能量IE(G)等于关联矩阵I (G)的奇异特征值之和.关联能量与能量关系密切. 本文根据n,m,最大度,最小度以及第一Zagreb 指标,给出关联能量新的上界,即IE(G)≤ 等.
- Abstract:
-
The incidence energy E(G)of G is the sum of the singular values of incidence matrix I (G).The incidence energy of graph is closely connected with the energy of graph.In this paper,new upper bounds for incidence energy in terms of n,m,maximum degree,minimum degree,and the first Zagreb index was given,ie,E(G)≤ and so on.
