Abstract :
In [13] Gutman introduced a novel graph invariant called Sombor index SO, defined as SO(G) = ΣeijϵE(G)√ deg(vi)^2 + deg(vj)^2. In this paper we provide relations between Sombor index and some degree-based topological indices: Zagreb indices, Forgotten index and Randić index. Similar relations are established in the class of triangle-free graphs.
