Geometry and Topology Seminar
Knot Invariants from Zero-Dimensional QFT
Dror Bar-Natan
Please join us for the next installment of the Geometry and Topology seminar series.
This time we will have Dror Bar-Natan (University of Toronto) speaking, so it's bound to be
interesting!
We will be going out for lunch after the talk.
Title:
Knot Invariants from Zero-Dimensional QFT
Abstract:
For the purpose of today, an "I-Type Knot Invariant" is a knot invariant computed from a knot diagram by integrating the exponential of a pertubed Gaussian Lagrangian which is a sum over the features of that diagram (crossings, edges, faces) of locally defined quantities, over a product of finite dimensional spaces associated to those same features.
