Abstract
Existing investigations dedicated to the self-propelling investigation of dynamics of bulk viscous string in LRS Bianchi type-I cosmological model within the circumstance of alternative theory of gravity with Langrangian be the impulsive perform of Ricci scalar R and Gouss-Bonnet invariant G , say f(R,G) gravity. Exact solutions of the field equations correspond to special law of variation which provides singular model. Also some physical and kinematical aspects and its behavior with the present day universe of the cosmological model have been discussed.
Highlights
Modified gravity is one among the foremost promising candidates for explaining the present fast enlargement of the Universe, and even its unification with the inflationary epoch
Behavior of Hubble parameter and the expansion scalar of a dynamics of bulk viscous string cosmological model versus time with the acceptable selection of constants as shown within the following Fig. 7 and Fig. 8 While observing the equation (30) and (31) it is clear that both Hubble parameter and the expansion scalar are the reciprocal function of exponential terms and it is observed that it is decreasing with time that means at t=0 the Hubble parameter and expansion scale moving towards infinity
In the vigorous exploration of spatially unvaried and anisotropic locally rotationally symmetric Bianchi type-I cosmological model with dynamics of bulk viscous string provide among the framework of f (R,G) theory of gravity at t 0, the model of the universe is constant and metric potentials ne'er approaches to vanishing worth
Summary
Modified gravity is one among the foremost promising candidates for explaining the present fast enlargement of the Universe, and even its unification with the inflationary epoch. Santhi et al [13] determined f (R) gravity field conditions with the assistance of a spatially homogeneous and anisotropic Bianchi type-III space-time, within the sight of a mass thick liquid, containing one-dimensional enormous strings. Smash and Kumari [17] introduced nonparticular Bianchi types I and V cosmological models, within the sight of mass gooey liquid and inside the structure of f (R,T ) gravity hypothesis. 124, 925 (1961)) field conditions with the assistance of a spatially homogeneous and anisotropic Bianchi type-VI0 metric, within the sight of a mass gooey liquid, containing one-dimensional enormous strings. Shekh [28] introduced examination committed to the dynamical examination of anisotropic DE LRS Bianchi type-I cosmological model with regards to changed gravity in which Langrangian be the discretionary capacity of Ricci scalar and Gouss-Bonnet invariant say f (R, G) gravity in the way of anisotropic fluid. Singh and Baro [33] researched Bianchi Type-I string cosmological model with mass thick liquid and negative consistent deceleration boundary in everyday relativity
