Presentations of Bordism Categories

Filippos Sytilidis
(University of Oxford)
Abstract

A topological quantum field theory (TQFT) is a functor from a category of bordisms to a category of vector spaces. Classifying low-dimensional TQFTs often involves considering presentations of bordism categories in terms of generators and relations. In this talk, we will introduce these concepts and outline a program for obtaining such presentations using Morse–Cerf theory.

Mirzakhani Society

Hello all, we are the Mirzakhani Society, a group for all the women and non-binary mathematicians at Oxford. We run lots and lots of relaxed events from pizza nights to career conferences. Our main aim is to create a warm and welcoming environment for women* to come together and chat about life, maths and anything in-between.

The musical instruments we play

Did you know that nearly 40 early career researchers in the department actively play a musical instrument? If you haven't told us yet about your extra-mathematical talents, especially faculty, please let Dyrol know which instrument you play. We may (may) do a feature next term on maths and music. You know, get a band together, that sort of thing.
