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. All rights reserve
