Non-Extremal D-instantons and the AdS/CFT Correspondence
E. Bergshoeff, A. Collinucci, A. Ploegh +2
We investigate non-extremal D-instantons in an asymptotically background and the role they play in the correspondence. We find that the hologra…
An index for the Dirac operator on D3 branes with background fluxes
Eric Bergshoeff, Renata Kallosh, Amir-Kian Kashani-Poor +2
We study the problem of instanton generated superpotentials in Calabi-Yau orientifold compactifications directly in type IIB string theory. To this end, we derive the Dirac equatio…
IIB Supergravity Revisited
Eric A. Bergshoeff, Mees de Roo, Sven F. Kerstan +1
We show in the SU(1,1)-covariant formulation that IIB supergravity allows the introduction of a doublet and a quadruplet of ten-form potentials. The Ramond-Ramond ten-form potentia…
Cosmological D-instantons and Cyclic Universes
E. A. Bergshoeff, A. Collinucci, D. Roest +2
For models of gravity coupled to hyperbolic sigma models, such as the metric-scalar sector of IIB supergravity, we show how smooth trajectories in the `augmented target space' conn…
