No periodic orbits for the type A Bianchi's systems
(Taylor & Francis Ltd, 2015-01-01)
It is known that the 6 models of Bianchi class A have no periodic solutions. In this article we provide a new, direct, unified and easier proof of this result.

Anisotropic k-essence cosmologies
(American Physical Society, 2006-03)
We investigate a Bianchi type-I cosmology with k-essence and find the set of models which dissipate the initial anisotropy. There are cosmological models with extended tachyon fields and k-essence having a constant barotropic ...
Bianchi IX cosmologies in the Einstein-Skyrme system in a sector with nontrivial topological charge
(2019)
The dynamics of the most general Bianchi IX cosmology with three time dependent scale factors for the Einstein-Skyrme system are analyzed. For the Skyrmion, a generalized hedgehog ansatz with unit baryon charge is introduced. ...

Ecuación de desvío geodésico en cosmologías de Bianchi y sus implicaciones cosmológicas
(2010)
Últimamente los datos de la Radiación Cósmica de Fondo (RCF) han dado como resultado anomalías o desviaciones con respecto al modelo estándar de la cosmología, lo cual ha llevado a varios cosmólogos a considerar modelos ...
