摘要：
The main purpose of this paper is to study the Laplacian eigenvalues of the extension of the zero divisor graph, Gamma e ( Z n ) , for some particular values of n . We characterize the values of n that give the equality of the spectral radius and the second -smallest eigenvalue of Gamma e ( Z n ). Finding Wiener index of Gamma e ( Z n ) in terms of its Laplacian eigenvalues is another objective of this paper. (c) 2024 Elsevier B.V.
