Teleparallel gravity (TG) has significantly increased in popularity in recent decades, bringing
attention to Einstein's other theory of gravity. In this Review, we give a comprehensive …

The occurrences of singularities where spacetime curvature becomes infinite and geodesic
evolution breaks down are inevitable events in classical general relativity (GR) unless one …

An improved version of the well-known Peebles-Vilenkin model unifying early inflationary
era to current cosmic acceleration, is introduced in order to match with the theoretical values …

Considering as usual that the underlying geometry of our universe is well described by the
spatially flat Friedmann–Lemaître–Robertson–Walker line element, we review how the …

A union of matter bounce and ekpyrotic scenarios is often studied in an attempt to combine
the most promising features of these two models. Since nonperturbative quantum geometric …

We consider the Arnowitt-Deser-Misner formalism as a tool to build bouncing cosmologies.
In this approach, the foliation of the spacetime has to be fixed in order to go beyond general …

In this work we investigate which Loop Quantum Cosmology (LQC)-corrected Gauss–
Bonnet F (𝒢) gravity can realize two singular cosmological scenarios, the intermediate …

Abstract The Dapor–Liegener model of loop quantum cosmology (LQC), which depicts an
emergent universe from a de Sitter regime in the contracting phase is studied from the …

Bouncing cosmologies are obtained by adding to the Einstein–Hilbert action a term of the
form-\, gf (χ)-gf (χ), with χ χ a scalar depending on the Hubble parameter only, not on its …

The theory of inflation is one of the fundamental and revolutionary developments of modern
cosmology that became able to explain many issues of the early Universe in the context of …
