چکیده
|
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 nseeleft(gright) =sum_{i=1}^{n}e^{gamma _{i}^{+}}. some lower bounds on %nseeleft( gright) are also established.
