Super Riemann Surfaces Revisited
Gelfand Centennial Conference:
A View of 21st Century Mathematics
MIT, Room 34-101, August 28 - September 2, 2013
Abstract:
I will recall the definition of a super Riemann surface, and the role that they play in superstring theory. I will describe recent work with R. Donagi showing that the moduli stack of super Riemann surfaces cannot be holomorphically projected to the moduli stack
of ordinary Riemann surfaces. This roughly means that super Riemann surfaces cannot be described in terms of ordinary Riemann surfaces in an elementary way.
