Interacting quintessence dark energy models in Lyra manifold

Understand

In this paper, we consider two-component dark energy models in Lyra manifold.

• The first component is assumed as a quintessence field while the second model may be a viscous polytropic gas, a viscous Van der Waals gas or a viscous modified Chaplygin gas.
• We also consider the possibility of interaction between components.
• By using numerical analysis, we study some cosmological parameters of the models and compare them with observational data.
