Let \(M\) be a unitary left \(R\)-module where \(R\) is a ring with identity. The co-intersection graph of proper submodules of \(M\), denoted by \(\Omega(M)\), is an undirected simple graph whose the vertex set \(V(\Omega)\) is a set of all non-trivial submodules of \(M\) and there is an edge betwe...
