D-instantons, Quantum mirror symmetry and Integrability Auteur(s): Alexandrov S.
Conférence invité: Topological Strings, Modularity and non-perturbative Physics (Vienna, AT, 2010-07-19) Ref HAL: hal-00506437_v1 Exporter : BibTex | endNote Résumé: I'll present recent results on the non-perturbative description of the hypermultiplet moduli space of compactified Type II string theory. The geometry of the moduli space gets instanton corrections due to D-branes and I'll show how one can describe all these D-instantons using the twistor approach to quaternionic geometries. These results are used to get a quantum completion of the classical mirror map and to show a deep relation of the twistor description of D-instantons to integrability. |
