【Abstract】 This paper discusses the distribution property of the edge independent indices of trees and forests of a given order. It is shown that the star graph and S 2 n-2 have respectively the largest and the second largest edge independent indices, while the path and T n have respectively the smallest and the second smallest edge independent indices.更多还原
