چکیده
|
Let γ be a graph with adjacency eigenvalues λ1 ≤ λ2 ≤ . . . ≤ λn. then the energy of γ, a concept defined in 1978 by gutman, is defined as e (g) = ∑n |λi|. 0 by ernesto estrada, is defined as ee(γ) = cayley graphs on generalized dihedral groups. as an application, we compute these items for honeycomb toroidal graphs and cayley graphs on dihedral groups.
