Cosmological phase space of R^n gravity
Alejandro Aviles Cervantes, Jorge L. Cervantes-Cota
We present some exact solutions and a phase space analysis of metric -gravity models of the type . We divide our discussion in and models. The later mod…
Gravitational Lensing in the metric theory proposed by Sobouti
Tula Bernal, Sergio Mendoza
Recently, Y. Sobouti (2007) has provided a metric theory f(R) that can account for certain dynamical anomalies observed in spiral galaxies. Mendoza & Rosas-Guevara (2007) have show…
Quasi-local variables and inhomogeneous cosmological sources with spherical symmetry
Roberto A. Sussman
We examine a large class of inhomogeneous spherically symmetric spacetimes that generalize the Lemaitre-Tolman-Bondi dust solutions to nonzero pressure ("LTB spacetimes"). Local co…
Leptogenesis in Complex Hybrid Inflation
Carlos Martinez Prieto
We study the transference of an initial leptonic charge contained in a complex scalar field (waterfall field) at the end of the inflation to the leptons of the standard model and t…
