Examples of stationary BPS solutions in N=2 supergravity theories with R^2-interactions

G. L. Cardoso, B. de Wit, J. Käppeli +1

We discuss explicit examples of BPS solutions in four-dimensional N=2 supergravity with R^2-interactions. We demonstrate how to construct solutions by iteration. Generically, the p…

D1/D5 systems in string theories

E. Gava, A. B. Hammou, J. F. Morales +1

We propose CFT descriptions of the D1/D5 system in a class of freely acting Z_2 orbifolds/orientifolds of type IIB theory, with sixteen unbroken supercharges. The CFTs describing D…

de Sitter Brane Gravity: from Close-Up to Panorama

Maulik K. Parikh, Sergey N. Solodukhin

We find explicitly the induced graviton propagator on de Sitter branes embedded in various five-dimensional spacetimes; de Sitter branes in AdS and Minkowski space are particular c…

Hidden Symmetries, Central Charges and All That

Bernard de Wit, Hermann Nicolai

In this review we discuss hidden symmetries of toroidal compactifications of eleven-dimensional supergravity. We recall alternative versions of this theory which exhibit traces of…

Gravity in Warped Compactifications and the Holographic Stress Tensor

Sebastian de Haro, Kostas Skenderis, Sergey N. Solodukhin

We study gravitational aspects of Brane-World scenarios. We show that the bulk Einstein equations together with the junction condition imply that the induced metric on the brane sa…

M-theory duality and BPS-extended supergravity

Bernard de Wit

We discuss toroidal compactifications of maximal supergravity coupled to an extended configuration of BPS states which transform consistently under the U-duality group. Under certa…
