RUSTY SCATTER BRANES

We derive double-dimensional reduction/oxidation in a framework where it is applicable to describe general nonstatic (and anisotropic) p-bra ne solutions. Given this procedure, we are able to relate the dynamica l interaction potential for parallel extremal p-branes in D dimensions to that for extremal black holes in D - p dimensions. In particular, we find that to leading order the potential vanishes for all kappa-sym metric p-branes.
