A NOTE ON SEGRE TYPES OF SECOND-ORDER SYMMETRIC TENSORS IN 5-D BRANE-WORLD COSMOLOGY
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 that the matter fields are confined on a brane-world embedded in five dimensions (the bulk). Motivated by this we re-examine the classification of …
