Seminar November 8 – Haggai Nuchi

On November 8th, Haggai Nuchi of the University of Pennsylvania will speak in the the Geometry-Topology Seminar.  He will speak about:

Title: Geometry of triple linking

Abstract: Gauss produced a formula for the linking number of a 2-component link in Euclidean space. This formula involves an integral with the property that the integrand is geometrically natural, i.e. it remains unchanged under rigid motions of the link. I will describe joint work producing an analogous integral formula for the Milnor triple linking number of a three-component link in Euclidean space, with the property that the integrand is again geometrically natural.
