Towards complete string effective actions beyond leading order
Kasper Peeters, Pierre Vanhove, Anders Westerberg
We review the current knowledge of higher-derivative terms in string effective actions, the various approaches that have been used to obtain them and their applications.
Anti-de-Sitter vacua require fermionic brane charges
Kasper Peeters, Marija Zamaklar
We argue that a modification of the super-AdS algebras which accounts for the presence of D-branes requires not only the inclusion of bosonic brane charges, but also the inclusion…
The Ramond-Ramond sector of string theory beyond leading order
Kasper Peeters, Anders Westerberg
Present knowledge of higher-derivative terms in string effective actions is, with a few exceptions, restricted to the NS-NS sector, a situation which prevents the development of a…
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…
