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…
Primordial synchronization of Mixmaster spatial points
Spiros Cotsakis
We review recent work on the possibility of primordial synchronization of different Mixmaster regions in generic inhomogeneous spacetime. It is shown that inhomogeneous domains und…
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…
Geodesic incompleteness and partially covariant gravity
Ignatios Antoniadis, Spiros Cotsakis
We study the issue of length renormalization in the context of fully covariant gravity theories as well as non-relativistic ones such as Hořava-Lifshitz gravity. The difference of…
