Higher Holonomy

13 Apr 2026. Talk by Jaime Pedregal at the meeting Young Researchers in Generalized Geometry, Hamburg University.

Abstract: In this brief introduction to higher holonomy, I will sketch how the classical holonomy group is hiddenly a 2-group, and how this perspective makes sense of the isotropy terms appearing in Fernandes’s version of the Ambrose–Singer theorem for Lie algebroid holonomy. Towards the end, if time allows, I will say a few words about higher holonomy in general.
