the relationship between the sombor index and other topological indices

Gutman recently introduced a new vertex-degree-based topological index called the sombor index. it is a vertex-degree-based topological index and is denoted by sombor index, so(g) = p uv∈e(g) √d2 u + d2 v, where du is the degree of vertex u in g. in this paper, we obtain some result on the bounds of the sombor index in terms of some other topological indices.
