Abstract

Define the zeroth-order Randić index \(R^0(G)=\sum _{x\in V(G)}\frac{1}{\sqrt{d_G(x)}}\), where \(d_G(x)\) denotes the degree of the vertex x. In this paper, we present two sufficient conditions for graphs and triangle-free graphs to be super-edge-connected in terms of the zeroth-order Randić index, respectively.
