Abstract

We obtain, via the Gauss–Codazzi formalism, the expression of the effective Einstein–Brans–Dicke projected equations in a non-ℤ₂ symmetric braneworld scenario which presents hybrid compactification. It is shown that the functional form of such equations resembles the one in the Einstein case, except for the fact that they bring about extra information in the context of exotic compactifications.
