Locality and Integration in Topological Field Theory
Daniel S. Freed
Abstract
This paper is an expanded version of a talk given at the XIX International Colloquium on Group Theoretical Methods in Physics, Salamanca, July, 1992. We discuss the geometry of topological terms in classical actions, which by themselves form the actions of topological field theories. We first treat the Chern-Simons action directly. Then we explain how the geometry is best understood via integration of smooth Deligne cocycles. We conclude with some remarks about the corresponding quantum theories in 3 and 4 dimensions. This paper is written using AMSTeX 2.1, which can be obtained via ftp from the American Mathematical Society (instructions included).
