Vassiliev Invariants and Chern-Simons Theory: Pedagogical Review and
Some Recent Results
Esther Pérez
U. Alfonso X
Topological Chern-Simons field theory has proved a very powerfull
tool to study Vassiliev invariants of knots and links. The perturbative
evaluation of the Wilson loop operator in different gauges provides equivalent
representations of the invariants, each related with a different matematical
approach. The aim of the talk is to give a brief review on the subjet, and then
describe some new results, focusing on the analysis in the temporal gauge
where, despite the well known ambiguities of this gauge, very simple
combinatorial expressions for the invariants are encountered.
The almuerzo-seminario is
intended to be an informal seminar and an open forum for discussion.
You are wellcome to bring your own
