Energy and Wiener index of divisor graph of commutative ring

In recent paper, P. D. Khandare et al. introduced a graphical structure of non empty finite ring R called as divisor graph D[R] and discussed some properties of the graph D[Z(n)]. In this article, we will continue the study of the divisor graph D[Z(n)]. Z and discuss some more properties of D[Z(n)]. If n is an element of N then we derive general formula for total degree and stability number of n is an element of Z Moreover we find adjacency matrix of the graph D[Z(n)]. and derived formula for energy of D[Z(n)] when n = p(k), k is an element of N and n = pq, for primes p and q.
