Abstract
The 3D index is an invariant for cusped 3-manifolds introduced by Dimofte-Gaiotto-Gukov in 2011, which seems to contain a lot of information about the topology and geometry of the manifold. After a brief introduction, I'll describe our q-hypergeometric approach to study the behaviour of this invariant under Dehn filling. This is joint work with C. Hodgson and H. Rubinstein.
About Pure mathematics seminars
We present regular seminars on a range of pure mathematics interests. Students, staff and visitors to UQ are welcome to attend, and to suggest speakers and topics.
Seminars are usually held on Tuesdays from 2 to 3pm.
Talks comprise 45 minutes of speaking time plus five minutes for questions and discussion.
Information for speakers
Researchers in all pure mathematics fields attend our seminars, so please aim your presentation at a general mathematical audience.
