Abstract :
Let G and H be simple graphs and |V(G)| = n. The corona of two graphs, denoted by G ◦ H, is the graph obtained by taking one copy of graph G and n copies of H and joining the ith vertex of G to every vertex of the ith copy of H. Let S (G) be the subdi-vision of graph G. In this paper we define four new subdivision coronas of two graphs and find the characteristic and Laplacian polynomials of them in case of regularity.
