The mathcal{N} = 4 effective action of type IIA supergravity compactified on SU(2)-structure manifolds
Abstract
We study compactifications of type IIA supergravity on six-dimensional manifolds with SU(2) structure and compute the low-energy effective action in terms of the non-trivial intrinsic torsion. The consistency with gauged mathcal{N} = 4 supergravity is established and the gauge group is determined. Depending on the structure of the intrinsic torsion, antisymmetric tensor fields can become massive.
