We consider the problem of gravitational forces between point particles on the branes in a Randall-Sundrum (R-S) two brane model with S 1 /Z 2 symmetry. Matter is assumed to produce a perturbation to the R-S vacuum metric and all the 5D Einstein equations are solved to linearized order (for arbitrary matter on both branes). We show that while the gauge condition h i5 = 0, i = 0, 1, 2, 3 can alw...

We derive properties of the radial evolution of scalar fields in anti-de Sitter spacetime from quantum mechanics, through a factorisation of the path integral. We describe why we anticipate application of these results to the AdS/CFT correspondence.

Noncommutative three-dimensional gravity can be described in terms of a noncommuta-tive Chern-Simons theory. We extend this structure and also propose an action for gravi-tational fields on an even dimensional noncommutative space. The action is worked out in some detail for fields on a noncommutative CP 2 and on S 4 .
