In this work, we obtain good upper bounds for the diameter of any graph in terms of its minimum degree and its order, improving a classical theorem due to Erdos, Pach, Pollack and Tuza. We use these bounds in order to... 详细信息

Erratum to “On a Classical Theorem on the Diameter and Minimum Degree of a Graph”
收藏 引用
Acta Mathematica Sinica,English Series 2018年 第12期34卷 1907-1910页
作者: Vernica HERNáNDEZ Domingo PESTANA José M.RODRíGUEZ Departamento de Matemáticas Universidad Carlos Ⅲ de Madrid
The original version of the article was published in [1]. Unfortunately, the original version of this article contains a mistake: in Theorem 6.2 appears that β(n, △) = (n-△ + 5)/4 but the correct statement is... 详细信息
