Twistors, CFT and Holography
Kirill Krasnov
According to one of many equivalent definitions of twistors a (null) twistor is a null geodesic in Minkowski spacetime. Null geodesics can intersect at points (events). The idea of…
On the Uniqueness of Plane-wave String Field Theory
A. Pankiewicz, B. Stefanski
We prove that the two interaction Hamiltonians of light-cone closed superstring field theory in the plane-wave background present in the literature are identical.
Mapping the vacuum structure of gauged maximal supergravities: an application of high-performance symbolic algebra
Thomas Fischbacher
The analysis of the extremal structure of the scalar potentials of gauged maximally extended supergravity models in five, four, and three dimensions, and hence the determination of…
On non-perturbative extensions of anti-de-Sitter algebras
Patrick Meessen, Kasper Peeters, Marija Zamaklar
Motivated by the study of branes in curved backgrounds, we investigate the construction of non-perturbative extensions of the super-isometry algebra osp*(8|4) of the AdS_7xS^4 back…
