QM Introductory Seminar: Supermanifolds, Super Riemann surface, and supermoduli space

Speaker: Nadia Ott (University of Southern Denmark)


Abstract:

I will give an introductory talk on supermanifolds, super Riemann surfaces, and supermoduli space, starting with the definitions of these objects. I will then introduce a current area of research in supergeometry, super period matrices, and state two famous results in the field: Donagi and Witten’s proof that supermoduli space is not split for genus g ≥ 5, and D’Hoker and Phong’s calculation of the genus g = 2 superstring amplitude.
