Notes on 1- and 2-Gerbes

  • Lawrence Breen
Part of the The IMA Volumes in Mathematics and its Applications book series (IMA, volume 152)


The aim of these notes is to discuss in an informal manner the construction and some properties of 1- and 2-gerbes. They are for the most part based on the author’s texts [1–4]. Our main goal is to describe the construction which associates to a gerbe or a 2-gerbe the corresponding non-abelian cohomology class.
