From a hydrodynamicist's point of view the inclusion of viscosity concepts in the macroscopic
theory of the cosmic fluid would appear most natural, as an ideal fluid is after all an …

The objective of this work enclosed with the study of spatially homogeneous anisotropic
Bianchi type-I universe in f (R, T) gravity (where R is the Ricci scalar and T is the trace of …

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\(T\) …

We test a cosmological model which the only component is a pressureless fluid with a
constant bulk viscosity as an explanation for the present accelerated expansion of the …

We explore the viability of a bulk viscous matter-dominated Universe to explain the present
accelerated expansion of the Universe. The model is composed by a pressureless fluid with …

Thepresent study deals with spatially homogeneous and anisotropic Bianchi-I cosmological
models representing massive strings with variable G and decaying vacuum energy density …

Abstract The Friedmann–Robertson–Walker Universe containing viscous fluid and matter
creation is considered in the modified f (R, T) theory of gravitation, which is an arbitrary …

Einstein's field equations with variable gravitational and cosmological “constant” are
considered in presence of perfect fluid for Bianchi type-I space-time. Consequences of the …

In this work, we study a flat Friedmann–Robertson–Walker universe filled with dark matter
and viscous new holographic dark energy. We present four possible solutions of the model …

Some cylindrically symmetric inhomogeneous viscous fluid string cosmological models with
magnetic field and cosmological term Λ varying with time are investigated. To get the …
