Given a collection A of hyperplanes in $\mathbb{C}^n$, the corresponding Milnor fibre is the hypersurface $\Prod_{H\in A} \alpha_H=1$, where $H= Ker(\alpha_H)$. Its geometry is connected with many deep questions in representation theory and Lie theory. I will explain how to compute its Euler characteristic with local coefficients, and indicate how this leads to a plethora of unsolved problems. 

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.
