A Note on Segre Types of Second Order Symmetric Tensors in 5-D Brane-world Cosmology
M. J. Reboucas, J. Santos
Recent developments in string theory suggest that there might exist extra spatial dimensions, which are not small nor compact. The framework of most brane cosmological models is th…

What do very nearly flat detectable cosmic topologies look like?
B. Mota, G. I. Gomero, M. J. Reboucas +1
Recent studies of the detectability of cosmic topology of nearly flat universes have often concentrated on the range of values of given by current observations. Here we stu…

Constraints on the Detectability of Cosmic Topology from Observational Uncertainties
B. Mota, M. J. Reboucas, R. Tavakol
Recent observational results suggest that our universe is nearly flat and well modelled within a CDM framework. The observed values of and inevitably involve uncer…
