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…
