Abstract

Let G = (V, E) be a graph. We define matrices M(G; α, β)as αD + βA, where α, β are real numbers such that (α, β) ≠ (0, 0) and D and A are the diagonal matrix and adjacency matrix of G, respectively. Using the largest and smallest eigenvalues of M(G; α, β) with α≥ β> 0, we present sufficient conditions for the Hamiltonian and traceable graphs.
