Coronae Graphs and Their α-Eigenvalues

Let G 1 and G 2 be two simple connected graphs. The properties of α - eigenvalues of four coronal graphs of G 1 and G 2 : G 1 ∘ G 2 , G 1 ◊ G 2 , G 1 ⊙ G 2 and G 1 ⊝ G 2 have been studied. As an application, we construct infinitely many pairs of non-isomorphic graphs with the same α -eigenvalues....
