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
JC de Araujo, HGM Fortes - arxiv preprint arxiv:2407.08884, 2024 - arxiv.org
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) …
