The covariant formulation of f(T) gravity
(Iop Publishing Ltd, 2016-06-09)
We show that the well-known problem of frame dependence and violation of local Lorentz invariance in the usual formulation of f(T) gravity is a consequence of neglecting the role of spin connection. We re-formulate f(T) ...
ASYMPTOTIC PROPERTIES OF A SUPPOSEDLY REGULAR (DIRAC-BORN-INFELD) MODIFICATION OF GENERAL RELATIVITY

Teleparallel theories of gravity: illuminating a fully invariant approach
(Iop Publishing Ltd, 2019-09-19)
Teleparallel gravity and its popular generalization f(T) gravity can be formulated as fully invariant (under both coordinate transformations and local Lorentz transformations) theories of gravity. Several misconceptions ...
Slow-roll inflation in f(R,T) gravity and a modified Starobinsky-like inflationary model
(2021)
In this work, we studied the slow-roll approximation of cosmic inflation within the context of f (R,T) gravity, where R is the scalar curvature, and T is the trace of the energy-momentum tensor. By choosing a minimal ...
Neutron stars in Scalar-Tensor-Vector Gravity
(Springer, 2017-02)
Scalar-Tensor-Vector Gravity (STVG), also referred as Modified Gravity (MOG), is an alternative theory of the gravitational interaction. Its weak field approximation has been successfully used to describe Solar System ...
Smooth braneworld models possibility in modified gravities
(World Scientific Publ Co Pte Ltd, 2015-10-01)
In this paper, it is shown that the consideration of the braneworld consistency conditions within the framework of bulk modified gravities allows for the existence of thick branes in the five-dimensional case with compact ...
Reconstruction of f(r, t) gravity describing matter dominated and accelerated phases
(2012)
We investigate the cosmological reconstruction in modified f(R, T) gravity, where R is the Ricci scalar and T the trace of the stress–energy tensor. Special attention is attached to the case in which the function f is given ...
