Laplacian polynomial and Kirchhoff index of some graphs generated by a cycle
Fatma El-Safty, 2025, original scientific article

Abstract: In this paper, a new formula for Kirchhoff index of a graph is presented and applied to some graphs derived from a cycle of length n through investigating their Laplacian polynomials.
Keywords: cycle graph, Laplacian polynomial, Kirchhoff index
