Graphs Whose Aα -Spectral Radius Does Not Exceed 2

Let A(G) and D(G) be the adjacency matrix and the degree matrix of a graph G, respectively. For any real α ∈ [0, 1], we consider Aα (G) = αD(G) + (1 − α)A(G) as a graph matrix, whose largest eigenvalue is called the Aα -spectral radius of G. We first show that the smallest limit point for the Aα -sp...
