Localizing branes with bifurcating bulks
Ignatios Antoniadis, Spiros Cotsakis, John Miritzis
We study the problem of evolution of bulk 5-fluids having an embedded braneworld with a flat, de Sitter, or anti-de Sitter geometry. We introduce new variables to express the Einst…
Regular braneworlds with bulk fluids
Ignatios Antoniadis, Spiros Cotsakis, Ifigeneia Klaoudatou
We review studies on the singularity structure and asymptotic analysis of a 3-brane (flat or curved) embedded in a five-dimensional bulk filled with a `perfect fluid' with an equat…
Brane-world asymptotics in a nonlinear fluid bulk
Ignatios Antoniadis, Spiros Cotsakis, Ifigeneia Klaoudatou
We present recent results on the asymptotics of a brane-world that consists of a flat 3-brane embedded in a five-dimensional bulk. The bulk matter is modelled by a fluid that satis…
Regular braneworlds with nonlinear bulk-fluids
Ignatios Antoniadis, Spiros Cotsakis, Ifigeneia Klaoudatou
We construct a regular five-dimensional brane-world with localised gravity on a flat 3-brane. The matter content in the bulk is parametrised by an analog of a non-linear fluid with…
The singularity problem in brane cosmology
Ignatios Antoniadis, Spiros Cotsakis
We review results about the development and asymptotic nature of singularities in `brane-bulk' systems. These arise for warped metrics obeying the 5-dimensional Einstein equations…
Infinity in string cosmology: A review through open problems
Ignatios Antoniadis, Spiros Cotsakis
We review recent developments in the field of string cosmology with particular emphasis on open problems having to do mainly with geometric asymptotics and singularities. We discus…
