   created Chern-Simons 2-gerbe

   linked to it from principal infinity-bundle and Chern-Simons theory. In fact, I added an Idea-section to Chern-Simons theory.

   Format: MarkdownItexI suppose from there on one is to use something like * Claudio Pedrini, [[Charles Weibel]], _The higher K-theory of complex varieties_, K-theory 21 (2001), 367-385 ([web](http://www.math.uiuc.edu/K-theory/0403/)) to see how the K-theoretic string extension in the algebraic context base-changes to the ordinary string extension. But not tonight, need to call it quits now.
