abstract = {The Sombor index $(SO)$ is a recently invented vertex-degree-based molecular structure-descriptor. Let $M_1$ be the first Zagreb index. The fact that $SO$ is bounded from below by $M_{1}/\sqrt{2}$ and from above by $M_{1}$ is well-known and easy to prove. In this paper, we improve these bounds.},
