An Overview of Knots and Gauge Theory [video]


Abstract: The Jones polynomial of a knot, discovered in 1983, is a very subtle invariant that is related to a great deal of mathematics and physics. This talk will be an overview of quantum field theories in dimensions 2, 3, 4 and 5 that are intimately related to the Jones polynomial of a knot and a more contemporary refinement of it that is known as Khovanov homology.


Prof. Edward Witten, of the Institute for Advanced Study in Princeton, New Jersey, will present the Second Annual Peter Scherk Lecture in Geometry.
