A Metric Theory of Gravity with Torsion hidden in extra dimension
---
A metric theory of gravity with torsion hidden
in an extra-dimension is presented. With
a set of constraints, non-vanishing components
torsion and connection coefficients are expressed
in terms of metric components resulting in
modified Einstein equations. At the kinematic
level, the theory maps on to General Relativity,
but the dynamical field equations that follow
from the action principle deviate markedly
from the standard Einstein equations,whose
consequences on homogeneous, isotropic cosmology
and static, spherically symmetric vacuum
solutions will be discussed.
