### Abstract or Additional Information

Suppose that a compact Lie group G acts on a smooth manifold M. To any G-equivariant complex vector bundle with connection over M, there exist classical constructions of equivariant Chern forms and equivariant Chern classes. In my talk, I will explain how to use simple bundle constructions to produce this equivariant Chern-Weil theory from the ordinary non-equivariant theory. I will then explain how this naturally produces secondary Chern-Simons type invariants.
