We investigate the model-independent parameterization of H (z) in spatially homogeneous
and isotropic FLRW space-time using Cosmic Chronometers (31 data points) and …

This study examines interacting quintessence dark energy models and their observational
constraints for a general parameterization of the quintessence potential, which …

Our current observations have not definitively determined the exact form of the expansion
factor of spacetime. It is possible that we are experiencing a transitional stage of expansion …

This paper explores the evolution of the overdense region of dark matter in the presence of a
nonminimally coupled scalar field which is used to model quintessence and phantomlike …

Dynamical system theory is a widely used technique in the analysis of cosmological models.
Within this framework, the equations describing the dynamics of a model are recast in terms …

We study the evolution of k=-1 FLRW cosmological models for two interacting Dark Matter-
Dark Energy Models using dynamical system analysis. Since we are interested in late time …

This study extends two phenomenological models of dark energy within the framework of
Finsler–Randers space–time, accommodating anisotropies. The models consider the …

In this paper, we have outlined the development of an autonomous dynamical system within
a general scalar-tensor gravity framework. This framework encompasses the overall …

Tachyons or hypothetical faster-than-light (FTL) particles would fail the principle of causality.
Such particles may only be imagined when they have no energy and momentum and, thus …

We investigate the interaction between the dark sectors from a dynamical systems
perspective. A general setup for interacting dark energy models that incorporates both …
