An Investigation of Equivalence between Bulk-based and Brane-based
Approaches    [PDF]

There are two different approaches to handle brane-world models brane-based or bulk-based. In the brane-based approach, the brane is chosen to be fixed on a coordinate system, whereas in the bulk-based approach, it is no longer static as it moves along the extra dimension. It is aimed to get a general formalism of the equivalence between two approaches obtained for a specific model in Mukohyama et all [12]. We found that calculations driven by a general anisotropic bulk-based metric yields a brane-based metric in Gaussian Normal Coordinates by conserving spatial anisotropy.
