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…
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…
The causal order on the ambient boundary
Ignatios Antoniadis, Spiros Cotsakis, Kyriakos Papadopoulos
We analyse the causal structure of the ambient boundary, the conformal infinity of the ambient (Poincaré) metric. Using topological tools we show that the only causal relation comp…
