Seiberg duality (swapping NS5-branes)
A variant of the idea of generalized complex geometry given by passing from generalization of complex geometry to generalization of exceptional geometry. Instead of by reduction of structure groups along inclusions like $O(d)\times O(d) \to O(d,d)$ it is controled by inclusions into split real forms of exceptional Lie groups.
This serves to neatly encode U-duality groups in supergravity as well as higher supersymmetry of supergravity compactifications. See also at exceptional field theory for more on this.
Compactification of 11-dimensional supergravity on a manifold of dimension 7 preserves $N = 1$ supersymmetry precisely if its generalized tangent bundle has G-structure for the inclusion
of the special unitary group in dimension 7 into the split real form of E7. This is shown in (Pacheco-Waldram 08).
One dimension down, compactification of 10-dimensional type II supergravity on a 6-manifold $X$ preserves $N = 2$ supersymmetry precisely if the generalized tangent bundle $T X \otimes T^* X$ in the NS-NS sector admits G-structure for the inclusion
This is reviewed in (GLSW, section 2).
