The purpose of this article was to examine the behavior of the Little rip (LR) and Pseudo rip (PR) models with two interacting ideal fluids related to dark energy and dark matter with the quadratic equation of state with time-dependent parameters $\omega(t)$ and $\Lambda(t)$ in flat Friedmann–Lemaitre–Robertson–Walker cosmological model. In this article, the gravitational equations of motion for dark matter have been solved. The equation of the state parameter $\omega(t)\to -1$ has been discovered. Also, discovered $\Lambda(t)\to 1$ as $t\to \infty$, it shows that the future behavior of our universe depends on specific model parameters $\omega(t)$ and $\Lambda(t)$ for the coupled dark energy. In this formalism, the properties of the early universe are pointed out.

Continuous Article Publishing mode
Since January 2016, the Journal of Astrophysics and Astronomy has moved to Continuous Article Publishing (CAP) mode. This means that each accepted article is being published immediately online with DOI and article citation ID with starting page number 1. Articles are also visible in Web of Science immediately. All these have helped shorten the publication time and have improved the visibility of the articles.
