Interacting new agegraphic viscous dark energy with varying $G$

Understand

We consider the new agegraphic model of dark energy with a varying gravitational constant, $G$, in a non-flat universe.

• We obtain the equation of state and the deceleration parameters for both interacting and noninteracting new agegraphic dark energy.
• We also present the equation of motion determining the evolution behavior of the dark energy density with a time variable gravitational constant.
• Finally, we generalize our study to the case of viscous new agegraphic dark energy in the presence of an interaction term between both dark components.
