摘要：

In [13] Gutman introduced a novel graph invariant called Sombor index SO, defined as SO(G) = Sigma eij is an element of E(G) root deg(v(i))(2) + deg(v(j))(2). In this paper we provide relations between Sombor index and some degree-based topological indices: Zagreb indices, Forgotten index and Randic index. Similar relations are established in the class of triangle-free graphs. (C) 2021 University of Kashan Press. All rights reserved
