Q&A session: Friday 15:00-16:00.



Abstract:

In this mini-course, I will discuss some approaches to the geometry of supersymmetric field theory that offer promising new perspectives on issues related to M-theory, in particular on eleven-dimensional supergravity and six-dimensional theories with (2,0) supersymmetry. One key ingredient will be a structural analogy between superspaces and almost-complex manifolds, which allows for a unified formulation of supersymmetric theories and their twists. Another will be the notion of factorization current algebra and the factorization Noether theorem of Costello and Gwilliam. By the end, I hope to have reviewed both some recent progress and some outstanding questions related to twisted eleven-dimensional supergravity.
