The main goal of this work is to provide a comprehensive study of relativistic structures in the
context of recently proposed R+ α A gravity, where R is the Ricci scalar, and A is the anti …

Unlike F (R) gravity, pure F (T) gravity in the vacuum dominated era does not produce any
form, viable to study cosmological evolution. Factually, it does not even produce any …

We study early universe with a particular form of F (T) teleparallel gravity theory, in which
inflation is driven by a scalar field. To ensure slow rollover, two different potentials are …

Einstein–Hilbert action is supplemented by the Gauss–Bonnet squared term, its phase-
space structure is constructed and canonical quantization is performed. Resolution of a …

A viable radiation-dominated era in the early universe is best described by the standard
(FLRW) model of cosmology. In this short review, we demonstrate reconstruction of the forms …

We study the quantum evolution of the early Universe, its semi-classical analogue together
with inflationary regime, in view of a generalized modified theory of gravity. The action is …

Whether Jordan's and Einstein's frame descriptions of F (R) theory of gravity are physically
equivalent, is a long standing debate. However, practically none questioned on true …

Unlike the Noether symmetry, a metric independent general conserved current exists for non-
minimally coupled scalar–tensor theory of gravity if the trace of the energy-momentum tensor …

Gauss–Bonnet-dilatonic coupling in four dimensions plays an important role to explain late-
time cosmic evolution. However, this term is an outcome of the low energy string effective …
