Laplacian spectral properties of nilpotent graphs over ring Z_n
We consider a ring with unity. The nilpotent graph of is a graph with vertex set ; and two distinct vertices and are adjacent iff , where is the set of all nilpotent elements of and it is denoted by. In this paper we study Laplacian spectral properties of the nilpotent graph over the ring .
