| dc.description | We write out the geodesic deviations that take place in a $d\geq 4$ dimensional brane world subspace of a higher dimensional spacetime by splitting out the brane and the extra space dynamical quantities from a global metric spacetime of dimension $D\geq 5$. The higher dimensional dynamical quantities are projected onto two orthogonal subspaces, where one of which is identified with a $(d-1)$-brane. This is done by using some technics of the conventional submanifold theory of the Riemannian geometry, applied to pseudo-Riemannian spaces. Using the splitting technic, we obtain the tidal field on $(d-1)$ branes with an arbitrary number of non compact extra dimensions. Later, we analise the geodesic deviations seen by an ordinary observer in a $d=4$ dimensional spacetime and show that deviations from general relativity tidal field due to the existence of the extra dimensions can appear because, (i) - the dependence of the indunced metric on the brane with the extra coordinates and (ii) - deviations of the higher dimensional spacetime metric from spherical symmetry. | |
