Brane constructions, fractional branes and anti-de Sitter domain walls

Compactifications of type IIB string theory on AdS(5) X X-5, where X-5 is an Einstein space, can have one-fourth or half maximal supersymmetry for certain choices of X-5. Some of these theories admit exotic domain walls arising from 5-branes wrapping 2-cycles in X-5. We explore the relationship among these domain walls, fractional branes and branes stretched on intervals. World-volume fluxes in the wrapped branes play an important role in the analysis. We draw some parallels between the AdS background with exotic domain walls and N = 1 supersymmetric MQCD, and identify other extended objects on the AdS side in the dual brane construction. The process of brane creation is used to give an alternate derivation of the relationship between fractional branes and branes on intervals.
