KT and HKT Geometries in Strings and in Black Hole Moduli Spaces
G. Papadopoulos
Some selected applications of KT and HKT geometries in string theory, supergravity, black hole moduli spaces and hermitian geometry are reviewed. It is shown that the moduli spaces…
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…
The IIA super-eightbrane
E. Bergshoeff, M. B. Green, G. Papadopoulos +1
We present a version of ten-dimensional IIA supergravity containing a 9-form potential for which the field equations are equivalent to those of the standard, massless, IIA theory f…
Global Aspects of Symmetries in Sigma Models with Torsion
G. Papadopoulos
It is shown that non-trivial topological sectors can prevent the quantum mechanical implementation of the symmetries of the classical field equations of sigma models with torsion.…
