Ricci flow solutions that are defined for all negative times have a special significance and are called ancient. Many instances in the literature indicate that ancient solutions possess more symmetries than initially assumed. In this talk, we describe the general structure of collapsed ancient solutions to the homogeneous Ricci flow on compact manifolds and we show that, under some algebraic assumptions, they are, additionally, invariant under the right action of a torus T that centralizes the isotropy group H. This is joint work with S. Sbiti and A. M. Krishnan.

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.
