The minimum Sombor index of trees with given number of pendant vertices

V Maitreyi, S Elumalai, S Balachandran… - Computational and Applied …, 2023 - Springer
For any graph G, the Sombor index is defined as SO (G)=∑ uv∈ E (G) d G 2 (u)+ d G 2 (v),
where d G (u) is the degree of the vertex u in G. In this paper, we determine the minimum …
