Over the past decade, f (R) theories have been extensively studied as one of the simplest
modifications to General Relativity. In this article we review various applications of f (R) …

Abstract Euclid is a European Space Agency medium-class mission selected for launch in
2020 within the cosmic vision 2015–2025 program. The main goal of Euclid is to understand …

Beyond Einstein's Gravity is a graduate level introduction to extended theories of gravity and
cosmology, including variational principles, the weak-field limit, gravitational waves …

In this paper, we reconstruct cosmological models in the framework of f (R, T) gravity, where
R is the Ricci scalar and T is the trace of the stress-energy tensor. We show that the dust …

We investigate the main features of the flat Friedmann-Lemaître-Robertson-Walker
cosmological<? format?> models in the f (T) modified gravity regime. In particular, a general …

The purpose of the current article is to present a brief albeit accurate presentation of the
main tools used in the study of symmetries of Lagrange equations for holonomic systems …

We study rapid-turn trajectories in a class of two-field cosmological models, whose scalar
manifold is the Poincaré disk. Background solutions in multi-field inflation, with field-space …

We propose to use a model-independent criterion based on first integrals of motion, due to
Noether symmetries of the equations of motion, in order to classify the dark energy models in …

This paper investigates the Noether symmetry approach in modified f (ℛ, φ, χ) theory of
gravity, where ℛ is the Ricci scalar, φ is a scalar field and χ is the kinetic energy term. For …
