Homoclinic chaos in the dynamics of a general Bianchi IX model
H. P. de Oliveira, A. M. Ozorio de Almeida, I. Damião Soares +1
The dynamics of a general Bianchi IX model with three scale factors is examined. The matter content of the model is assumed to be comoving dust plus a positive cosmological constan…

Galerkin Method in the Gravitational Collapse: a Dynamical System Approach
H. P. de Oliveira, I. Damião Soares
We study the general dynamics of the spherically symmetric gravitational collapse of a massless scalar field. We apply the Galerkin projection method to transform a system of parti…

Density perturbations in warm inflation and COBE normalization
H. P. de Oliveira
Starting from a gauge invariant treatment of perturbations an analytical expression for the spectrum of long wavelength density perturbations in warm inflation is derived. The adia…
