چکیده
Let G be a graph of order n, A(G) its adjacency matrix and D(G) the diagonal degrees G. In 2017, for every α in [0, 1], Nikiforov defined Aα(G) = αD(G) + (1 − α)A(G). this paper, we investigate Aα-spectrum graphs obtained from duplicate corona operations. As an application our results, provide conditions construction some pairs non isomorphic Aα-cospectral graphs.

The Laplacian Spectrum of Corona of Two Graphs
Let G1,G2 be two connected graphs. Denote the corona and the edge corona of G1, G2 by G1 ◦ G2 and G = G1 G2, respectively. In this paper, we compute the Laplacian spectrum of the corona G◦H of two arbitrary graphs G and H and the edge corona of a connected regular graph G1 and an arbitrary graph G2.
متن کاملEla the Spectrum of the Edge Corona of Two Graphs
Abstract. Given two graphs G1, with vertices 1, 2, ..., n and edges e1, e2, ..., em, and G2, the edge corona G1 ⋄G2 of G1 and G2 is defined as the graph obtained by taking m copies of G2 and for each edge ek = ij of G, joining edges between the two end-vertices i, j of ek and each vertex of the k-copy of G2. In this paper, the adjacency spectrum and Laplacian spectrum of G1 ⋄ G2 are given in te...

15 صفحه اولD-Spectrum and D-Energy of Complements of Iterated Line Graphs of Regular Graphs
The D-eigenvalues {µ1,…,µp} of a graph G are the eigenvalues of its distance matrix D and form its D-spectrum. The D-energy, ED(G) of G is given by ED (G) =∑i=1p |µi|. Two non cospectral graphs with respect to D are said to be D-equi energetic if they have the same D-energy. In this paper we show that if G is an r-regular graph on p vertices with 2r ≤ p - 1, then the complements of iterated lin...
