Web28 de set. de 2024 · Let G be a simple undirected graph. For real number α ∈ [0, 1], Nikiforov defined the A α -matrix of G as A α (G) = αD(G) + (1 − α)A(G), where A(G) and D(G) are the adjacency matrix and the degree diagonal matrix of G respectively. In this paper, we obtain a sharp upper bound on the largest eigenvalue ρ α (G) of A α (G) for α … WebScribd is the world's largest social reading and publishing site. 5. FLOOR PLACEMENTS.
