Cosmic Behavior, Statefinder Diagnostic and $w-w^{\prime}$ Analysis for Interacting NADE model in Non-flat Universe
Abstract
We give a brief review of interacting NADE model in non-flat universe. we study the effect of spatial curvature , interaction coefficient and the main parameter of NADE, , On EoS parameter and deceleration parameter . We obtain a minimum value for in both early and present time, in order to that our DE model crosses the phantom divide. Also in a closed universe, changing the sign of is strongly dependent on . It has been shown that the quantities and have a different treatment for various spatial curvature. At last, we calculate the statefinder diagnostic and analysis in non flat universe. In non flat universe, the statefinder trajectory is discriminated by both and .
