May 23 The category of (local) lifting data Abstract
In a series of talks I will try to sketch the various ways to think about (holomorphic) gerbes.
· As sheaves of categories
· As principal bundles with fibre a classifying space
· In terms of presentation/atlas
· By gerbe data
If there is interest and time, we will also discuss some basic things about Bfields.
We are going to stay mostly in the analytic category, or in the algebraic category /C,
with occasional discussions of topological aspects.
