Opers and the E6 Minahan-Nemeschansky theory

Regular Seminar Lotte Hollands (Heriot-Watt U., Edinburgh)

13:15 KCL
room K4.31

In this seminar I explain a geometric proposal to determine a nonperturbative partition function for the E6 Minahan-Nemeschansky theory. Important ingredients are generating functions of opers, spectral networks and a generalisation of complex Fenchel-Nielsen coordinates to moduli spaces of higher rank flat connections. (This is joint work with Andy Neitzke.)
