Abstract:
We consider nearly Kähler six-manifolds with a two-torus symmetry. We construct a multi-moment map for the torus action and describe its general properties. At regular values, the action is necessarily free on the level sets and determines the geometry of three-dimensional quotients. Finally we give a result on an inverse construction producing nearly Kähler six-manifolds from three-dimensional data.​
