Besides our research seminars, we also organise a reading seminar. Sometimes we have a theme, in which we attempt to understand an important theory. Alternatively, people students present papers they have read, in an informal atmosphere. The goal is to broaden everyone’s expertise, and to make it easier to stay on top of recent developments in a range of subjects.
The schedule for this term is below; when a title is a link clicking it will take you to an abstract. The list of previous reading seminars is also available.
The Kapustin-Witten equation
The reading seminar this term will study the following papers by Rafe Mazzeo and Edward Witten: https://arxiv.org/abs/1311.3167 and https://arxiv.org/abs/1712.00835 . Here is a video introduction to the papers by Rafe Mazzeo https://mathinstitutes.org/videos/videos/1580 .
The papers study the Kapustin-Witten equation, a new gauge-theoretic equation in some ways similar to the instanton equation, and their relation with knot invariants on 3-manifolds. You may also like the following introductory notes and papers about the KW equations by Uhlenbeck https://web.stanford.edu/~ljfred4/Attachments/TempleLectures.pdf and Uhlenbeck and Gagliardo https://arxiv.org/abs/1401.7366.
We are currently organising the schedule and it will be posted here when it is ready.
