초록
A topological index of a chemical structure (graph) is a number that correlates the chemical structure with chemical reactivity or physical properties. There are several topological indices have been defi ned on graphs using degrees of vertices/edges, for instance fi rst and second Zagreb indices. In this paper, we introduce a new topological index for graphs called Tosha index using tension on edges. Further, we establish some inequalities and compute Tosha index for some standard graphs.
