Ramond-Ramond (boundary) states
M. Billo, R. Russo
The description of D-branes as boundary states for type II string theories (in the covariant formulation) requires particular care in the R-R sector. Also the vertices for R-R pote…
The rigid limit in Special Kahler geometry; From K3-fibrations to Special Riemann surfaces: a detailed case study
Marco Billo, Frederik Denef, Pietro Fre +4
The limiting procedure of special Kahler manifolds to their rigid limit is studied for moduli spaces of Calabi-Yau manifolds in the neighbourhood of certain singularities. In two e…
Special geometry of Calabi-Yau compactifications near a rigid limit
Marco Billo, Frederik Denef, Pietro Fre +4
We discuss, in the framework of special Kahler geometry, some aspects of the "rigid limit" of type IIB string theory compactified on a Calabi-Yau threefold. We outline the general…
A detailed case study of the rigid limit in Special Kähler geometry using K3
Marco Billo, Frederik Denef, Pietro Fre +4
This is a résumé of an extensive investigation of some examples in which one obtains the rigid limit of N=2 supergravity by means of an expansion around singular points in the modu…
