Abstract [English]

Gutman proposed a new alternative interpretation of vertex-degree-based topological index, called Sombor index. It is defined via the term . In this paper, we determine the explicit expressions of Sombor index for line and total graphs and several pericondensed benzenoid hydrocarbons.
