The quaternionic/hypercomplex-correspondence
arXiv:1904.06056
Abstract
Given a quaternionic manifold with a certain -symmetry, we construct a hypercomplex manifold of the same dimension. This construction generalizes the quaternionic Kähler/hyper-Kähler-correspondence. As an example of this construction, we obtain a compact homogeneous hypercomplex manifold which does not admit any hyper-Kähler structure. Therefore our construction is a proper generalization of the quaternionic Kähler/hyper-Kähler-correspondence.
