Supersymmetric heterotic string backgrounds
Ulf Gran, George Papadopoulos, Diederik Roest
We present the main features of the solution of the gravitino and dilatino Killing spinor equations derived in hep-th/0510176 and hep-th/0703143 which have led to the classificatio…
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…
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.…
