چکیده
|
The sombor index of the graph $g$ is a degree based topological index, defined as $so = sum_{uv in mathbf e(g)}sqrt{d_u^2+d_v^2}$, where $d_u$ is the degree of the vertex $u$, and $mathbf e(g)$ is the edge set of $g$. bounds on $so$ are established in terms of graph energy, size of minimum vertex cover, matching number, and induced matching number.
