Lectures on n-Categories and Cohomology
John Baez and Michael Shulman
http://arxiv.org/abs/math.CT/0608420
The goal of these talks was to explain how cohomology and other
tools of algebraic topology are seen through the lens of n-category
theory. Special topics include nonabelian cohomology, Postnikov
towers, the theory of "n-stuff", and n-categories for n = -1 and -2.
The talks were very informal, and so are these notes. A lengthy
appendix clarifies certain puzzles and ventures into deeper waters
such as higher topos theory. For readers who want more details,
we include an annotated bibliography.
