For a finite commutative ring $\mathbb {Z} _ {n} $ with identity $1\neq 0$, the zero divisor
graph $\Gamma (\mathbb {Z} _ {n}) $ is a simple connected graph having vertex set as the …

For a simple graph G, the generalized adjacency matrix A α (G) is defined as A α (G)= α D
(G)+(1− α) A (G), α∈[0, 1], where A (G) is the adjacency matrix and D (G) is the diagonal …

Let G be a connected graph with n vertices, m edges. The distance signless Laplacian
matrix DQ (G) is defined as DQ (G)= Diag (Tr (G))+ D (G), where Diag (Tr (G)) is the diagonal …

Let G be a finite group and a G be the conjugacy class of a∈ G. The commuting conjugacy
class graph of G is a simple undirected graph, denoted by Γ G, whose vertex set is {a G: a∈ …
