Abstrakt: Let G be a simple connected graph of order n with m edges. Denote by + 1 γ≥ + 2 γ≥ . . . ≥ + n γ≥ 0 the normalized signless Laplacian eigenvalues of G. In this work, we define the normalized signless Laplacian Estrada index of G as NSEE (G) = Pn i=1 e+ i: Some lower bounds on NSEE (G) are also established. [ABSTRACT FROM AUTHOR]
