Co-unit graphs associated to ring of integers modulo <i>n</i>

Abstract Let R be a finite commutative ring. We define co-unit graph, associated to ring , denoted by G nu ( ) with vertex set V )) = U ), where is the of units and two distinct vertices x y being adjacent if only + ∉ / ). In this paper, we investigate some basic properties integers modulo n, for different values n. find domination number, clique number girth
