Abstract
Let G be a simple connected graph of order n with m edges. Denote by % \gamma _{1}^{+}\geq \gamma _{2}^{+}\geq \cdots \geq \gamma _{n}^{+}\geq 0 the normalized signless Laplacian eigenvalues of G. In this work, we define the normalized signless Laplacian Estrada index of G as NSEE\left(G\right) =\sum_{i=1}^{n}e^{\gamma _{i}^{+}}. Some lower bounds on %NSEE\left( G\right) are also established.
