The Early Universe
This line of research faces the study of the classical primordial Universe as described via more general models than the Robertson-Walker geometry.
Particular attention is devoted to the asymptotic behavior towards the initial singularity of the Bianchi Universes, as well as of the generic (inhomogeneous) cosmological solution.
The study of chaotic cosmologies is also addressed when a Mixmaster-like dynamics is recovered and their properties are analyzed in detail.
