| Abstract: | 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. |
