S-Duality, SL(2,Z) Multiplets and Killing Spinors
P. M. Llatas, J. M. Sanchez de Santos
The S-duality transformations in type IIB string theory can be seen as local U(1) transformations in type IIB supergravity. We use this approach to construct the multiple…

Worldvolume Dynamics of D-branes in a D-brane Background
J. M. Camino, A. V. Ramallo, J. M. Sanchez de Santos
We study the embedding of D(8-p)-branes in the background geometry of parallel Dp-branes for . The D(8-p)-brane is extended along the directions orthogonal to the Dp-branes…
