| Abstract: | A tree is called an r-leaves tree if it has r pendent vertices.The maximum and minimum values of the independent indices of 3-leaves trees and 4-leaves trees are investigated.3-leaves and 4-leaves trees,which have the maximum or minimum values of the independent indices,are characterized. |
| |
| Keywords: | the independent index r-leaves tree pendent vertices |
