Geometry and Topology Seminar
Finite type invariants of knots and links and manifold calculus of functors
Ismar Volic, Wellesley

I will present a topological construction which provides a new point of view on finite type knot and link invariants. Namely, a certain tower of spaces arising from Goodwillie-Weiss manifold calculus of functors turns out to be a classifying object for these invariants. After first reviewing the most important definitions and results from finite type theory, I will present the construction of the Goodwillie-Weiss tower for the space of knots, and then describe how finite type invariants factor through it. I will also mention some consequences of this result and at the end briefly discuss the Bott-Taubes integrals of configuration spaces which are central to the proof of the main theorem.
