树的第三小与第四小ABC能量
Trees with the Third and Fourth Minimum ABC Energy
摘要
Abstract
In order to find the trees with the third and fourth minimum ABC energy among all trees on n ≥13 vertices,the results of this problem are given by using edge deletion operation of graphs,the reduction of inequality and the corollary of the Coulson-type integral formula.The results show that among all tree of n ≥13 vertices,An and Bn are the unique tree with the third and fourth mini-mum ABC energy,respectively.The obtained results have certain reference value for the study of the ABC energy of extrema value problem of trees,and it is also useful to speculate on the properties of the relevant chemical molecular structure.关键词
