Interaction of polytropic dark energy in cosmological model: Constraints from observational data

Elangbam Chingkheinganba Meetei, S. Surendra Singh

We investigate an interacting polytropic dark energy (PDE) model characterised by the equation of state $p_d=\alpha {\rho }_d^{1+\frac{1}{\beta }}$, where the interaction between dark energy…
