We discuss nonminimally coupled cosmologies involving different geometric invariants.
Specifically, actions containing a nonminimally coupled scalar field to gravity described, in …

Discrepancies between observations at early and late cosmic epochs, and the vacuum
energy problem associated with the interpretation of cosmological constant, are …

This volume summarizes the many alternatives and extensions to Einstein's General Theory
of Relativity, and shows how symmetry principles can be applied to identify physically viable …

We explore the recently introduced modified Gauss–Bonnet gravity (Sharif and Ikram in Eur
Phys JC 76: 640, 2016), f (G, T) f (G, T) pragmatic with GG, the Gauss–Bonnet term, and T …

The debate on gravity theories to extend or modify general relativity is very active today
because of the issues related to ultraviolet and infrared behavior of Einstein's theory. In the …

The main purpose of this article is to analyze some physically viable solutions through the
Noether symmetry technique in f (R, T 2) theory. For this perspective, we assume a …

Swampland conjecture has recently been proposed to connect early time cosmological
models with the string landscape, and then to understand if related scalar fields and …

Adopting Noether point symmetries, we classify and integrate dynamical systems coming
from Horndeski cosmologies. The method is particularly effective both to select the form of …

Lovelock gravity in D-dimensional space-times is considered adopting Cartan's structure
equations. In this context, we find out exact solutions in cosmological and spherically …

Non-local gravity cosmologies are considered under the standard of Noether symmetry
approach. In particular, we focus on non-local theories whose gravitational actions depend …
