Lun. 10/12/2012 15:00 Petite Ourse, Bâtiment 13, Etage 1 ALEXANDROV Sergey (L2C) Twistor approach to string compactifications (Physique Théorique) I'll present an introduction to the problem of finding the low energy effective action for compactifications of string theory preserving N=2 supersymmetry. This problem reduces to the problem of describing the geometry of a certain moduli space which receives various quantum corrections. I'll show how these corrections can be efficiently described using twistor techniques. Pour plus d'informations, merci de contacter Crampé N. |
