The higher-order matching polynomial of a graph

International Journal of Mathematics and Mathematical Sciences, 2005
Given a graph G with n vertices, let p(G,j) denote the number of ways j mutually nonincident edges can be selected in G. The polynomial M(x)=∑j=0[n/2](−1)jp(G,j)xn−2j, called the matching polynomial of G, is closely related to the Hosoya index introduced

Maximal Ideal Graph of Zn

Zanco Journal of Pure and Applied Sciences
   In this paper, we present the structure of the maximal ideal graph of the ring . Several graph properties are given including completeness, planarity, separability. Furthermore, we show that  is Hamiltonian, and Eulerian under certain conditions.

Graph of Orthogonal Idempotent Elements in Rings of Integers Modulo n With Spectral Clustering

Journal of Mathematics
The zero-divisor graph provides a relationship between abstract algebra and graph theory. Based on this concept, a new graph is defined using the orthogonal idempotent elements in a ring.

Graphs Induced by W-Regular Rings With Application to Zpn

International Journal of Mathematics and Mathematical Sciences
A ring R is called W-regular if for any non-nilpotent element a of R, there exists an element b of R such that a=aba. This ring is generalized to a regular ring and is a special type of π-regular ring; therefore, some results on rings that are regular ...
