Thermodynamics and Perturbative Analysis of Some Newly Developed Theories Under the Scenario of Conserved Energy-momentum Tensor
M. Zubair, Saira Waheed, Quratulien Muneer +1
The present work is devoted to explore some interesting cosmological features of a newly proposed theory of gravity namely theory, where and represen…
Energy Constraints for Evolving Spherical and Hyperbolic Wormholes in Gravity
M. Zubair, Quratulien Muneer, Saira Waheed
The primary objective of this article is to study the energy condition bounds for spherical and hyperbolic wormholes in well-known theory of gravity. For this purpose, we…
Reconstruction and Stability Analysis of Some Cosmological Bouncing Solutions in Theory
M. Zubair, Quratulien Muneer, Saira Waheed
The present article investigates the possibility of reconstruction of the generic function in gravitational theory by considering some well-known cosmological bo…
Noncommutative inspired wormholes admitting conformal motion involving minimal coupling
M. Zubair, Saira Waheed, G. Mustafa +1
In this manuscript, we explore the existence of wormhole solutions exhibiting spherical symmetry in a modified gravity namely theory by involving some aspects of non-commu…
Szekeres Universes with Homogeneous Scalar Fields
John D. Barrow, Andronikos Paliathanasis
We consider the existence of an "inflaton" described by an homogeneous scalar field in the Szekeres cosmological metric. The gravitational field equations are reduced to two famili…
The past and future dynamics of quintom dark energy models
Genly Leon, Andronikos Paliathanasis, Jorge Luis Morales-Martínez
We study the phase space of the quintom cosmologies for a class of exponential potentials. We combine normal forms expansions and the center manifold theory in order to describe th…
