Journal ArticleDOI
New approach to find exact solutions for cosmological models with a scalar field.
TL;DR: In this paper, the cosmological models whose ordinary differential equations can be given a Lagrangian description on a two-dimensional configuration space were studied and it was shown that the potential must have an expotential form.
Journal ArticleDOI
Geometric classification of the torsion tensor in space-time
TL;DR: In this paper, two classification schemes for torsion are proposed, one based on the possibility to construct tensors from the product of a covariant bivector and a vector and their respective space-time properties, and the second one is obtained by starting from the decomposition of torsions into three irreducible pieces.
Journal ArticleDOI
f(R) gravity with torsion: the metric-affine approach
TL;DR: In this paper, the role of torsion in f(R) gravity is considered in the framework of metric-affine formalism, taking into account the analogy with the Palatini formalism.
Journal ArticleDOI
f(R) Cosmology with torsion
TL;DR: In this article, the authors derived the field equations in vacuum and in the presence of perfect-fluid matter and discussed the related cosmological models for f(R)-gravity with geometric torsion.
Journal ArticleDOI

TL;DR: The dynamics of a flat Friedmann-Robertson-Walker universe filled with a self-interacting scalar field nonminimally coupled to the gravitational field can be derived from a pointlike Lagrangian.
