Inflationary cosmology: theory and phenomenology
Classical and Quantum Gravity, 2002 This article gives a brief overview of some of the theory behind the inflationary cosmology, and discusses prospects for constraining inflation using observations. Particular care is given to the question of falsifiability of inflation or of subsets of inflationary models.

Navigating Permanent Underdetermination in Dark Energy and Inflationary Cosmology [PDF]
Philosophy of PhysicsWe identify troubling cases of so-called “permanent underdetermination” in both dark energy and inflationary cosmology. We bring to bear (a) a taxonomy of possible responses to underdetermination, and (b) an understanding of both dark energy and ...

INFLATIONARY COSMOLOGY FROM NONCOMMUTATIVE GEOMETRY [PDF]
International Journal of Modern Physics A, 1996 In the framework of the Connes-Lott model based on noncommutative geometry, the basic features of a gauge theory in the presence of gravity are reviewed, in order to show the possible physical relevance of this scheme for inflationary cosmology. These models naturally contain at least two scalar fields, interacting with each other whenever more than ...

Epistemic Justification and Methodological Luck in Inflationary Cosmology. [PDF]
Br J Philos Sci, 2019 I present a recent historical case from cosmology---the story of inflationary cosmology---and on its basis argue that solving explanatory problems can be a reliable method for making progress in science.

Constraining inflationary scenarios with braneworld models and second order cosmological perturbations [PDF]
, 2010 PhDInflationary cosmology is the leading explanation of the very early universe. Many different models of inflation have been constructed which fit current observational data.

Inflationary cosmology and thermodynamics [PDF]
Classical and Quantum Gravity, 1998 We present a simple and thermodynamically consistent cosmology with a phenomenological model of quantum creation of radiation due to vacuum decay. Thermodynamics and Einstein's equations lead to an equation in which $H$ is determined by the particle number $N$.

Post-inflationary brane cosmology
, 2001 The brane cosmology has invoked new challenges to the usual Big Bang cosmology. In this paper we present a brief account on thermal history of the post-inflationary brane cosmology. We have realized that it is not obvious that the post-inflationary brane

The dynamics of cosmological scenarios inspired by quantum gravity [PDF]
, 2006 PhDIn this thesis we study the dynamics of cosmological scenarios inspired by quantum gravity. Part I investigates novel features of the semi-classical regime of homogeneous and isotropic loop quantum cosmology.

Modulated reheating and large non-gaussianity in string cosmology [PDF]
, 2012 A generic feature of the known string inflationary models is that the same physics that makes the inflaton lighter than the Hubble scale during inflation often also makes other scalars this light.

STABLE INFLATIONARY DISSIPATIVE COSMOLOGIES [PDF]
International Journal of Modern Physics D, 2000 The stability of the de Sitter era of cosmic expansion in spatially curved homogeneous isotropic universes is studied. The source of the gravitational field is an imperfect fluid such that the parameters that characterize it may change with time. In this way we extend our previous analysis for spatially-flat spaces as well as the work of Barrow.
