Type II compactifications: effective action

We turn now to the structure of the effective action of type II orientifold compactifications. We mostly focus on the type IIA orientifolds of Chapter 10, and the type IIB models with D3/D7-branes (both in orbifolds, and magnetized) of Chapter 11, with brief discussions of D9/D5-brane models. We also often stick to one particular picture, relying on T-duality/mirror symmetry for the derivation of results in other constructions. We are mostly interested in 4d  = 1 compactifications, and hence focus on the Kähler potential K, the gauge kinetic functions fa, and the superpotential W. Although the effective ...
