  • May 30 Geometric bar construction -1 Abstract
  • 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.
