SUPERGRAVITY SOLUTIONS FOR BRANES LOCALIZED WITHIN BRANES

We construct supergravity solutions describing branes (D2-branes or NS 5-branes or waves) localized within D6-branes in the region close to the core of the D6-branes. Other similar string-theory and M-theory 'n ear-core' localized solutions can be found by applying U-duality and/o r lifting D = 10 solutions to D = 11. In particular, the D2-branes loc alized on D6-branes is T-dual to a special case of the background desc ribing (D)strings localized on (D)5-branes and thus is also related to a localized intersection of M2-branes and M5-branes. D6 + wave config uration is U-dual to a D0-brane localized on a Kaluza-Klein 5-brane or to the fundamental string intersecting a D5-brane with the point of i ntersection localized on D5-brane.
