Generating geodesic flows and supergravity solutions (2009)
Bergshoeff, E., Chemissany, W., Ploegh, A., Trigiante, M., Riet, T. Van
We consider the geodesic motion on the symmetric moduli spaces that arise after timelike and spacelike reductions of supergravity theories. The geodesics correspond to timelike respectively spacelike...
Generating Geodesic Flows and Supergravity Solutions (2008)
Bergshoeff, E., Chemissany, W., Ploegh, A., Trigiante, M., Van Riet, T.

Bergshoeff, E. A., Hartong, J., Ploegh, A., Sorokin, D.
We construct the half-supersymmetric instanton solutions that are electric-magnetically dual to the recently discussed half-supersymmetric Q7-branes. We call these instantons `Q-instantons'. Whereas...

Geodesic Flows in Cosmology (2008)
Bergshoeff, E., Chemissany, W., Ploegh, A., Riet, T. Van
In this brief note we discuss geodesic flows that correspond to cosmological solutions in higher-dimensional supergravity. On the one hand, we explain that S-brane solutions are in one-to-one...
Pseudo-supersymmetry and a Tale of Alternate Realities (2007)
Bergshoeff, E. A., Hartong, J., Ploegh, A., Rosseel, J., Bleeken, D. Van Den
We discuss how all variant 10d and 11d maximal supergravities, including star supergravities and supergravities in different signatures, can be obtained as different real slices of three complex...
Non-Extremal D-instantons and the AdS/CFT Correspondence (2005)
Bergshoeff, E., Collinucci, A., Ploegh, A., Vandoren, S., Van Riet, T.
We investigate non-extremal D-instantons in an asymptotically $ AdS_5 \times S^5$ background and the role they play in the $ AdS_5 / CFT_4$ correspondence. We find that the holographic dual operators...
Non-extremal D-instantons and the AdS/CFT correspondence (2005)
Bergshoeff, E., Collinucci, A., Ploegh, A., Vandoren, S., Riet, T. Van
We investigate non-extremal D-instantons in an asymptotically AdS5 × S5 background and the role they play in the AdS5/CFT4 correspondence. We find that the holographic dual operators of non-extremal...
