A model-independent compact dynamical system formulation for exploring bounce and cyclic cosmological evolutions in gravity
A. S. Agrawal, Charlotte Louw, Saikat Chakraborty +1
Using the dynamical systems approach together with the cosmographic parameters, we present a model-independent dynamical system formulation for cosmology in f(R) gravity. The formu…
Global phase space analysis for a class of single scalar field bouncing solutions in general relativity
A. S. Agrawal, Saikat Chakraborty, B. Mishra +2
We carry out a compact phase space analysis of a non-canonical scalar field theory whose Lagrangian is of the form within general relativity. In particular, we focus on…
Bouncing cosmological models in a functional form of F(R) gravity
A. S. Agrawal, S. Mishra, S. K. Tripathy +1
We have investigated some bouncing cosmological models in an isotropic and homogeneous space time with the F(R) theory of gravity. Two functional forms of F(R) have been investigat…
Observationally constrained accelerating cosmological model with higher power of non-metricity and squared trace
A. S. Agrawal, B. Mishra, S. K. Tripathy
In this paper, a cosmological model of the Universe is presented in gravity and the parameters are constrained by cosmological data sets. Initially, a generalised form of…
Matter Bounce Scenario in Extended Symmetric Teleparallel Gravity
A. S. Agrawal, B. Mishra, P. K. Agrawal
In this paper, we have shown the matter bounce scenario of the Universe in an extended symmetric teleparallel gravity, the f(Q) gravity. Motivated from the bouncing scenario and lo…
Unimodular Gravity Traversable Wormholes
A. S. Agrawal, B. Mishra, P. H. R. S. Moraes
Wormholes are outstanding solutions of Einstein's General Relativity. They were worked out in the late 1980's by Morris and Thorne, who have figured out a recipe that wormholes mus…
f(R) wormholes embedded in a pseudo--Euclidean space
A. S. Agrawal, B. Mishra, Francisco Tello-Ortiz +1
This work is devoted to the study of analytic wormhole solutions within the framework of gravity theory. To check the possibility of having wormhole structures satisfying en…
Bouncing cosmology in extended gravity and its reconstruction as dark energy model
A. S. Agrawal, Francisco Tello-Ortiz, B. Mishra +1
In this paper, we have presented a bouncing cosmological model of the Universe in an extended theory of gravity. The dynamical behaviour of the model obtained from the flat FLRW sp…
Matter Bounce Scenario and the Dynamical aspects in f(Q,T) Gravity
A. S. Agrawal, Laxmipriya Pati, S. K. Tripathy +1
In the context of the late time cosmic acceleration phenomenon, many geometrically modified theories of gravity have been proposed in recent times. In this paper, we have investiga…
Wormhole solutions in Gravity
B. Mishra, A. S. Agrawal, S. K. Tripathy. Saibal. Ray
In this work, we have studied the traversable wormholes geometry in theory gravity, where be the Ricci scalar. The wormhole solution for some assumed functions ha…
Gravitational baryogenesis models comparison in f(R) Gravity
A. S. Agrawal, S. K. Tripathy, B. Mishra
We have studied the gravitational baryogenesis in f(R) theory of gravity with an anisotropic Bianchi I space-time. The matter field is considered to be that of perfect fluid. Two m…
