Title：
The extended Bogomolny equations with Nahm pole boundary conditions
Abstract:
There is a well-known proposal by Witten that the Kapustin-Witten equations with Nahm pole type of boundary conditions can be related with knot invariants. While the Kapustin-Witten equations are generally hard to analyse, its local model: The extended Bogomolny equations are much easier. These equations are defined on X×(0,+∞), where X is a 3-dimensional manifold with possibly knotted points. In this talk, I will give an introduction on Witten's proposal and some studies on these equations.
