Groupoids, generalized Kahler structures, and (2,2) supersymmetry (Marco GUALTIERI, Toronto)

15.04.2025 15:00 – 17:00

It has recently become clear that the 2d supersymmetric sigma model has a hidden higher groupoid structure, which generalizes the appearance of the classifying stack BG in Chern-Simons theory. I will describe our recent work on this subject in https://arxiv.org/abs/2407.00831 and outline how the higher groupoids govern the behaviour of generalized Kahler metrics.
