Intersecting D-Branes in ten and six dimensions

arXiv:hep-th/9604168 · doi:10.1103/PhysRevD.55.3785

Abstract

We show how, via -duality, intersecting -Brane configurations in ten (six) dimensions can be obtained from the elementary -Brane configurations by embedding a Type IIB -Brane into a Type IIB Nine-Brane (Five-Brane) and give a classification of such configurations. We show that only a very specific subclass of these configurations can be realized as (supersymmetric) solutions to the equations of motion of IIA/IIB supergravity. Whereas the elementary -brane solutions in are characterized by a single harmonic function, those in contain two independent harmonic functions and may be viewed as the intersection of two elementary -branes. Using string/string/string triality in six dimensions we show that the heterotic version of the elementary -Brane solutions correspond in ten dimensions to intersecting Neveu-Schwarz/Neveu-Schwarz (NS/NS) strings or five-branes and their -duals. We comment on the implications of our results in other than ten and six dimensions.
