Singularities in any physical theory are either remarkable indicators of the unknown
underlying fundamental theory, or indicate a change in the description of the physical reality …

In this article, we have investigated the role of bulk viscosity to study the accelerated
expansion of the universe in the framework of modified f (Q) gravity. The gravitational action …

In this article, we consider an anisotropic viscous cosmological model having LRS Bianchi
type I spacetime with f (Q) gravity. We investigate the modified f (Q) gravity with form f (Q)= α …

This paper deals with an anisotropic cosmological model in the modified theory of f (Q)-
gravity filled with bulk-viscosity fluid. We investigated the modified f (Q)-gravity with quadratic …

In this paper, we introduce the bulk viscosity in the formalism of modified gravity theory in
which the gravitational action contains a general function\(f (R, T)\), where\(R\) and\(T\) …

In this study, we have investigated the dark energy behavior of the viscus-fluid in f (Q)-gravity
in a flat, isotropic and homogeneous Friedmann–Lemaitre–Robertson–Walker (FLRW) …

An entropic-force scenario, ie, entropic cosmology, assumes that the horizon of the Universe
has an entropy and a temperature. In the present paper, in order to examine entropic …

The bulk viscosity is introduced to model the current observational cosmos and the unified
dark matter (dark matter and dark energy). The viscous unified model assumes that the …

In this paper, we reconstruct an f (T) function from Λ CDM model and obtained field
equations for this function f (T)= T 2+ c 1 (− T) 1 2− 2 Λ in a flat FLRW viscous-fluid dusty …

We study two types of entropic-force models in a homogeneous, isotropic, spatially flat,
matter-dominated universe. The first type is a Λ (t) type similar to Λ (t) CDM (varying-lambda …
