Abstract

The Kragujevac trees where are used in molecular graphs have been studed by researchers of graph Theory in last years. In this paper, we study the characteristic polynomial and spectrum of adjacency and Laplacian matrices of regular Kragujevac trees. As application of our obtained results, we compute a upper bound for spectral redius, energy of graph and kirchhoff index.of Kragujevac trees.
