Abstract

We study specific problems in the theory of gravity, cosmology and models thereof. Concerning gravity, we consider perturbation of various solutions of Einstein gravity and generalizations (such as Horava gravity) and study the structure of the perturbations as well as the AdS/CFT relation as applied to condensed matter systems in the border. We also consider integrable systems on the border as related to gravity systems. Concerning cosmology, we concentrate in aspects of Dark Matter and Dark Energy, especially considering the interaction between the two dark sectors in relation to standard models of elementary particles.
