This article studies the effects of an arbitrary dark matter spin tensor on the propagation of
gravitational wave amplitude in the context of Einstein–Cartan theory. We choose to work …

A bstract In this paper, we formulate the Mimetic theory of gravity in first-order formalism for
differential forms, ie, the mimetic version of Einstein-Cartan-Sciama-Kibble (ECSK) gravity …

We study the evolution of scalar and tensor cosmological perturbations in the framework of
the Einstein–Cartan theory of gravity. The value of the gravitational slip parameter which is …

Allowing for a nonvanishing spin tensor for cold dark matter (ω DM= 0) has the consequence
of giving rise to an effective FLRW dynamics with a small negative barotropic constant for an …

By allowing torsion into the gravitational dynamics one can promote the cosmological
constant Λ to a dynamical variable in a class of quasitopological theories. In this paper we …

The current article offers a mathematical toolkit for the study of waves propagating on
spacetimes with nonvanishing torsion. The toolkit comprises generalized versions of the …

In this paper, we extend Shaposhnikov et al.'s parity violating the Einstein–Cartan–Holst
action by adding to Holst term H, a Proca photon–torsion coupling χ pt= 10− 24 as computed …

Minimal varying Λ theories are defined by an action built from the Einstein–Cartan–Holst first
order action for gravity with the cosmological constant Λ as an independent scalar field, and …

A cosmological approach based on considering a cosmic background with non-zero torsion
is shown in order to give an option of explaining a possible phantom evolution, not ruled out …

En esta tesis se estudia la propagación de las ondas gravitacionales en una teoría de
Einstein-Cartan-Sciamma-Kibble (ECSK) asumiendo un espacio tiempo con torsión …
