Let R (G) be the graph obtained from G by adding a new vertex corresponding to each edge of G and by joining each new vertex to the end vertices of the corresponding edge, and Q (G) be the graph obtained from G by inserting a new vertex into every edge of G and by joining by edges those pairs of these new vertices which lie on adjacent edges of G. In this paper, we determine the Laplacian polynomials of R (G) and Q (G) of a regular graph G; on the other hand, we derive formulae and lower bounds of the Kirchhoff index of these graphs.
