Super Edge-Connectivity and Zeroth-Order Randić Index

Define the zeroth-order Randić index as R0(G)=∑x∈V(G)1dG(x),{R^0}\left( G \right) = \sum\nolimits_{x \in V\left( G \right)} {{1 \over {\sqrt {{d_G}} \left( x \right)}},} where dG(x) denotes the degree of the vertex x. In this paper, we present two sufficient conditions for graphs and triangle-free g...
