Cosmic evolution in f (Q, T) gravity with observational constraints: A comparative analysis with ΛCDM
In this investigation, we explore the flat Friedmann-Lemaitre-Robertson-Walker (FLRW)
cosmological model within the framework of the f (Q, T) modified gravitation theory. This …

Transit dark energy models in Hoyle–Narlikar gravity with observational constraints
We discover the cosmic acceleration and physical characteristics of dark energy models in
Hoyle–Narlikar's theory of gravity with observational constraints. We identify analytical …

The Palatini formalism of the theory of gravity
We present the first formulation of the recently proposed f (R, L m, T) theory of gravity within
the Palatini formalism, a well-known alternative variational approach where the metric and …

Compact stars in gravity
General Relativity (GR) is not the only way gravity can be geometrised. Instead of curvature,
the Teleparallel Theory attributes gravity to torsion $ T $, which is related to the …

Two novel models
X Su, D He, Y Zhang - arxiv preprint arxiv:2408.03725, 2024 - arxiv.org
We propose two novel models in the framework of $ f (Q) $ gravity to explain our accelerated
universe, namely the exponential $ f (Q) _ {EXP} $ model and the hyperbolic tangent $ f (Q) …
