چکیده
|
The hosoya index z(g) of a graph g is the total number of matchings in it. in this paper, the recursive formulas of the hosoya index of semitotal graph q(g) and total graph t(g) for certain graphs g are obtained. moreover, we obtain the bounds of the hosoya index of semitotal and total graphs of a connected graph g.
