1. Análogos cosmológicos dos efeitos Schwinger estático e oscilatório / Cosmological Analogues of the Static and Oscillatory Schwinger Effect
In this work we study the quantum effects of particle creation in the cosmological context and of the classical electrodynamics. With the studies of the particle creation in constant and oscillatory external electrical fields, the known static and oscillatory Schwinger effects, respectively, it was possible to study the polarization of the quantum vacuum and

2. Inflationary cosmology in RS-I
In this work, I intend to show a possible candidate of inflaton potential V(phi) in a scenario of a brane world defined by a pair of branes (RS-I).

3. Nonlinear resonance in bouncing universes
The dynamics of closed LFRW universes with a massive inflaton field is examined where Friedmann equations are corrected by the introduction of a potential term arising from quantum gravity corrections to cosmological scenarios near the singularity. This extra term implements nonsingular bounces in the early evolution of the universe. For certain windows in t

4. Cosmologia inflacionária em modelos de branas tipo RS-I / Inflationary Cosmology in RS-I Brane Models.
A cosmologia inflacionária descreve uma fase durante a qual o nosso universo passou por expansão acelerada em um curto período de tempo a escalas de altas energias. A inflação soluciona os problemas deixados pelo modelo cosmológico da Grande Explosão, tais como os problemas de planura e do horizonte. Nesta fase, o nosso universo era governado por um p

5. Desnacionalização bancaria no Brasil (1997-2000)
This dissertation investigates the determinants and the impacts of banking denationalization in Brazil, caused by foreign bank entry in the retail banking market, beggining in 1997. First of all, I discuss foreign capital participation in the sector between the end of the XIX century and the eve of Real Plan implementation, in 1994, the period before recent

6. The inflationary effects of environmental fluctuations in source–sink systems
Ecological communities are open to the immigration of individuals and are variable through time. In open habitats immigration may permit populations of a species to persist locally even though local biotic and abiotic processes tend to exclude such “sink” populations. A general model for a sink population reveals that autocorrelated environmental variati
