Title: Low-dimensional higher geometry: a case study

Abstract:
Considerations from several different areas of mathematics have prompted 
the development of so- called higher geometry: the study of categorified 
analogues of geometric structures. Despite being studied for nearly two 
decades, few examples that capture non-abelian phenomena have been 
constructed. And here by "constructed", we mean to the level that would 
satisfy traditional differential geometers, as opposed to the kind of 
construction that category theorists are comfortable with.
To this end, I will describe a new framework to work with bundle 
2-gerbes, which from a higher- category point of view are certain types 
of truncated descent data for $\infty$-stacks on a manifold. The 
description is sufficient to undertake concrete computations more 
satisfying to traditional differential geometers and mathematical 
physicists. I also describe explicit geometric examples that can be 
constructed using our framework, including infinite families of explicit 
geometric string structures.
