چکیده
|
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.
