Einstein metrics on closed 4-manifolds with large isometry group
Speaker: Kyle Broder
Affiliation: University of Queensland
Abstract
I will present the results of my recent preprint (arXiv:2605.24859) on the classification of Einstein metrics on closed 4-manifolds whose isometry group has dimension at least 3. A consequence is a complete classification of cohomogeneity-one Einstein metrics on closed 4-manifolds: every such metric is either locally symmetric or homothetic to the Page metric on the blow-up of CP^2 at one point.
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.
