IIB solutions with N>28 Killing spinors are maximally supersymmetric
U. Gran, J. Gutowski, G. Papadopoulos +1
We show that all IIB supergravity backgrounds which admit more than 28 Killing spinors are maximally supersymmetric. In particular, we find that for all N>28 backgrounds the superc…
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…
IIB backgrounds with five-form flux
U. Gran, J. Gutowski, G. Papadopoulos
We investigate all N=2 supersymmetric IIB supergravity backgrounds with non-vanishing five-form flux. The Killing spinors have stability subgroups $Spin(7)\ltimes\bR^8$, $SU(4)\lti…
Geometry of all supersymmetric type I backgrounds
U. Gran, G. Papadopoulos, D. Roest +1
We find the geometry of all supersymmetric type I backgrounds by solving the gravitino and dilatino Killing spinor equations, using the spinorial geometry technique, in all cases.…
