The conformal cosmological potential

Spiros Cotsakis, Ifigeneia Klaoudatou, Georgios Kolionis +2

We discuss qualitative features of the conformal relation between certain classes of gravity theories and general relativity, common to different themes such as , Brans-Dicke…

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…

Curved branes with regular support

Ignatios Antoniadis, Spiros Cotsakis, Ifigeneia Klaoudatou

We study spacetime singularities in a general five-dimensional braneworld with curved branes satisfying four-dimensional maximal symmetry. The bulk is supported by an analog of per…

Enveloping branes and braneworld singularities

Ignatios Antoniadis, Spiros Cotsakis, Ifigeneia Klaoudatou

The existence of envelopes is studied for systems of differential equations in connection with the method of asymptotic splittings which allows to determine the singularity structu…
