Abstract

We study compactifications of type IIA supergravity on six-dimensional manifolds with SU2 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.
