Some basic properties of Sombor indices
İvan Gutman
Abstract
The recently introduced class of vertex-degree-based molecular structure descriptors, called Sombor indices (\(SO\)), are examined and a few of their basic properties established. Simple lower and upper bounds for \(SO\) are determined. It is shown that any vertex-degree-based descriptor can be viewed as a special case of a Sombor-type index.
