| چکیده | ||
| In 2021, a novel degree-based topological index was introduced by Gutman, called the Sombor index. Recently Kulli and Gutman introduced a vertex-edge variant of the Sombor index, is caled KG-Sombor index. In this paper, we establish lower bound on the KG-Sombor index and determine the extremal trees achieve this bound. | ||
