Supersymmetric extensions of affine Toda theories
A. Opfermann
It is shown that all affine Toda theories admit (1,0) supersymmetric extensions. The construction is based on classical Lie algebras and supersymmetric massive sigma models. The su…
Homogeneous HKT and QKT manifolds
A. Opfermann, G. Papadopoulos
We present the construction of a large class of homogeneous KT, HKT and QKT manifolds, , using an invariant metric on and the canonical connection. For this a decompositio…
T-duality and HKT manifolds
A. Opfermann
We examine conformal rescaling and T-duality in the context of four-dimensional HKT geometries. The closure of the torsion forces the conformal factor to satisfy a modified harmoni…
Twistor Spaces for QKT Manifolds
P. S. Howe, A. Opfermann, G. Papadopoulos
We find that the target space of two-dimensional (4,0) supersymmetric sigma models with torsion coupled to (4,0) supergravity is a QKT manifold, that is, a quaternionic Kähler mani…
