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 B-fields.
We are going to stay mostly in the analytic category, or in the algebraic category /C,
with occasional discussions of topological aspects.
