Categorical Deformation Theory, Vassiliev Theory and Other Topological Invariants
Yetter, David (Kansas State University)

We discuss the relationship between the deformation theory of monoidal categories, monoidal functors and monoidal natural transformations, both in relation to the classical algebraic deformation theory of Gerstenhaber and to its application to Vassiliev's finite-type invariants of classical knots and links.

Extensions to other topological applications in both three and four dimensions will be discussed.
