Dimensional reduction yields charge-independent metrics related to higher-dimensional Schwarzschild black holes.

The structure of intersecting black p-branes is closely connected to neutral Schwarzschild solutions.

Abstract

We comment on the structure of intersecting black p-brane solutions in string theory explaining how known solutions can be obtained from Schwarzschild solution simply by sequences of boosts and dualities. This implies, in particular, that dimensional reduction in all internal world-volume directions including time leads to a metric (related by analytic continuation to a cosmological metric) which does not depend on p-brane charges, i.e. is the same as the metric following by reduction from a higher-dimensional `neutral' Schwarzschild black hole.
