On Branes Ending on Branes in Supergravity
We study the eleven-dimensional supergravity and the classical solutions corresponding to M2-branes ending on M5-branes. We obtain the generic BPS configuration representing two sets of parallel M5-branes with (1+1) commonly longitudinal directions and M2branes stretching between them. We also discuss how the brane creation is described in supergravity. email address: [email protected]...
متن کاملD6 branes and M–theory geometrical transitions from gauged supergravity
We study the supergravity duals of supersymmetric theories arising in the world–volume of D6 branes wrapping holomorphic two–cycles and special Lagrangian three–cycles within the framework of eight dimensional gauged supergravity. When uplifted to 11d, our solutions represent M–theory on the background of, respectively, the small resolution of the conifold and a manifold with G2 holonomy. We fu...
متن کاملDomain walls of gauged supergravity, M-branes, and algebraic curves
We provide an algebraic classification of all supersymmetric domain wall solutions of maximal gauged supergravity in four and seven dimensions, in the presence of nontrivial scalar fields in the coset SL(8, IR)/SO(8) and SL(5, IR)/SO(5) respectively. These solutions satisfy first-order equations, which can be obtained using the method of Bogomol’nyi. From an eleven-dimensional point of view the...
متن کاملBranes, Calibrations and Supergravity
These notes are based on lectures given at the Clay School on Geometry and String Theory, Isaac Newton Institute, Cambridge, 25 March 19 April 2002. They attempt to provide an elementary and somewhat self contained discussion of the construction of supergravity solutions describing branes wrapping calibrated cycles, emphasising the geometrical aspects and focusing on D=11 supergravity. Followin...
متن کاملSupergravity 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 D6branes. Other similar string-theory and M-theory ‘near-core’ localized solutions can be found by applying U-duality and/or lifting D = 10 solutions to D = 11. In particular, the D2-branes localized on D6-branes is T-dual to a special case ...
