Semi localized brane intersections in SUGRA

We construct SUGRA solutions of brane configurations of intersecting Dp and NS branes. These solutions are semi-localized in the sense that one of the intersecting branes is smeared along the world volume of the other, while the second is localized. We examine the gauge theory that lives on the loca lized brans, and the various descriptions possible via T and S dualities, a nd M-theory. (C) 1999 Published by Elsevier Science B.V.
