|Titre||Quasiclassical BPS/CFT correspondence: from gauge theories to quantum groups|
|Horaire||17:00 à 18:00|
In recent years the remarkable connection between supersymmetric gauge theories and representation theory of infinite dimensional algebras including quantum affine algebras and Yangians, was discovered. I will review some aspects of this correspondence, in particular the role of q-characters in finding the low-energy effective theories.
