Cosmology and Cosmogony in a Cyclic Universe
Cosmology cosmogony high energy phenomena
font style='font-size:12px;'>
2009/5/12
In this paper we discuss the properties of the quasi-steady state
cosmological model (QSSC) developed in 1993 in its role as a cyclic model
of the universe driven by a negative energy scalar field. ...

2009/3/13
Development of the concept of fractal cosmos after Anaxagoras has
been followed up to the present. It is shown how the concept reappeared in the
early Renaissance as a vague idea and subsequently to...
Exact Solutions of Brans-Dicke Cosmology and the Cosmic Coincidence Problem
Brans-Dicke Cosmology the Cosmic Coincidence Problem

2010/10/15
We present some cosmological solutions of Brans-Dicke theory, characterized by a decaying vacuum energy density and by a constant relative matter density. With these features, they shed light on the c...
Inflationary Cosmology in RS-I
Inflationary Cosmology RS-I a brane world

2010/10/18
In this work, I intend to show a possible candidate of inflaton potential V(f) in a scenario of a brane world defined by a pair of branes (RS-I).

2010/10/13
Although most fundamental laws are invariant under time reversal, experience exhibits the presence of irreversible phenomena – the arrows of time. Their origin lies in cosmology, and I argue that only...

2010/10/26
A brief review of inflation is presented. After having demonstrated the generality of the inflationary mechanism, the emphasis is put on its simplest realization, namely the single field slow-roll inf...
