The unity product graph of a ring R is a graph which is obtained by setting the set of unit elements of R as the vertex set. The two distinct vertices ri and rj are joined by an edge if and only if ri · rj = e. The subgraphs of a unity product graph which are obtained by the vertex and edge deletion...
