Abstract
We study hyperkähler cones and their corresponding quaternion-Kähler
spaces. We present a classification of 4(n − 1)-dimensional quaternion-
Kähler spaces with n abelian quaternionic isometries, based on dualizing
superconformal tensor multiplets. These manifolds characterize the geometry
of the hypermultiplet sector of classical and perturbative moduli spaces
of type-II strings compactified on a Calabi-Yau manifold. As
