Higher-order Randić index and isomorphism of double starlike trees
For an integer $ h\geq 0 $, the $ h $th order Randić index for a simple graph $ G $ is defined as $ R^{h}(G) = \sum_{\pi}\frac{1}{\sqrt{v_1(\pi)v_2(\pi)\cdots v_{h+1}(\pi)}} $, where $ \pi $ extends over all paths of length $ h $ in $ G $ and $ v_i(\pi) $ denotes the degree of the $ i $-th vertex of...
