Connectedness and Distance Energy of Hamacher d-Fuzzy Graphs
摘要
Let \(\widetilde {G}\) be a fuzzy graph and \(A(\widetilde {G})\) be its adjacency matrix. The eigenvalues of \(A(\widetilde {G})\) are called eigenvalues of \(\widetilde {G}\) . The spectrum (Narayanan and Mathew, Ann Fuzzy Math Inform 6(3):455–465, 2013) of \(A(\widetilde {G})\) is called the spectrum of \(\widetilde {G}\) , denoted by \(Spec\widetilde {G}\) . The sum of the absolute values of eigenvalues of \(\widetilde {G}\) is considered as Energy (Narayanan and Mathew, Ann Fuzzy Math Inform 6(3):455–465, 2013) of \(\widetilde {G}\) . In this paper, Connectedness and Distance energy of Hamacher d-fuzzy graphs are obtained.
