Abstract: Let G be a graph. The graphs Tk(G) and Tk(G) are defined to be the subdivision of the k-inflation and k-triangulation of G, respectively. In this paper, formulas for the number of spanning trees and Kirchhoff indices of these graphs are obtained. These formulas are expressed in terms of graph invariants of G.
