Formation and analysis of self-gravitating structures: numerical, astrophysical, and cosmological problems


In the context of the modern cosmology the consequences of having a stochastic component in the density contrast function is considered, i.e., non-gaussian components of the density distribution are modeled using stochastic fields. N-body simulations in the presence of a massive central body are studied. Different schemas to consdier relativistic effects are presented. Also the formation of structures is studied via distribution functions solutions of Liouville equation and other related equations. We search for exact or numerical solution of Einsteins equations related to compact objects with astrophysical interest like disks, rings, etc. (AU)
