Conférence invité: Autumn Symposium on String/M-theory (Seoul, KR, 2014-09-22) Ref HAL: hal-01071271_v1 Exporter : BibTex | endNote Résumé: I propose to consider a new function on the moduli space of N=2 supersymmetruic gauge theories in 4 dimensions. It encodes the BPS spectrum of the theory and possesses many intersting properties which make it unique and one of the most natural objects to be studied. |
