The Sombor index for unicyclic and bicyclic graphs with given (total) domination number

The Sombor index is one of the vertex-degree-based topological indices that was introduced in ۲۰۲۱ by Gutman. In this paper we obtain some bounds of Sombor index of trees, unicyclic and bicyclic graphs with given (total) domination number.
