Abstract

It is shown that an HKT-space with closed parallel potential 1-form has D(2,1;1)D(2,1;-1)-symmetry. Every locally conformally hyperk\"ahler manifold generates this type of geometry. The HKT-spaces with closed parallel potential 1-form arising in this way are characterized by their symmetries and an inhomogeneous cubic condition on their torsion.
