Abstract
  In $1994,$ degree distance  of a graph was introduced by Dobrynin, Kochetova and Gutman. And Gutman proposed the Gutman index of a graph in $1994.$ In this paper, we introduce the concepts of  multiplicative version of degree distance and the multiplicative version of Gutman index of a graph. ...  Read More
The edge tenacity of a split graph

Bahareh Bafandeh Mayvan

Volume 47, Issue 1 , June 2016, , Pages 119-125

https://doi.org/10.22059/jac.2016.7950

Abstract
  The edge tenacity Te(G) of a graph G is de ned as:Te(G) = min {[|X|+τ(G-X)]/[ω(G-X)-1]|X ⊆ E(G) and ω(G-X) > 1} where the minimum is taken over every edge-cutset X that separates G into ω(G - X) components, and by τ(G - X) we denote the order of a ...  Read More
