直径为3的有向树的回归性的界

Range of Returnability with Diameter 3 of Directed Tree

回归性的概念是针对复杂有向网络提出的,它与图的谱有关.用χ(ck,D)表示复杂有向网络D的回归值,图G表示D的基础图,本文研究了直径为3的有向树的回归性的界,进一步缩小了回归值界的范围.

The concept of returnability is based on directed complex network presented,and it is related to spectrum.We use χ（ck,D） represents the returnability of the complex directed network D,Graph G show the based graph of D,this paper studies the range of returnability with diameter 3 of directed tree,which further narrows the range of returnability.
