Some Remarks on Harmonic Spaces

By definition, a Riemannian manifold M is called harmonic, if each point pM has a neigborhood U such that there is a non-constant harmonic function on U\p. Euclidean spaces and, more generally, two-point homogeneous spaces are harmonic. Conversely, the so-called Lichnerowicz conjecture states that any complete and simply connected harmonic manifold is two-point homogeneous. This was proved by Szabó in the compact case, in the non-compact case, Damek and Ricci found counterexamples. I will discuss the compact case.

Volumes of moduli spaces of algebraic curves

The moduli space of complex algebraic curves carry a natural Kähler structure given by the Weil-Petersson metric. The volumes of moduli spaces with respect to the Weil-Petersson metric are interesting invariants that appear naturally in both mathematics and theoretical physics. We propose a fast algorithm for computing Weil-Petersson volumes that leads to a conjectural formula for their large genus asymptotic behavior.

AMSI Summer School on Integral Geometry and Imaging

Thursday, September 3rd, 2009

The Departments of Mathematics and Physics is organising a summer school on Integral Geometry and Imaging in November. The line up of lecturers is world class, and we expect the exciting schedule of lectures to be of particular interest to mathematicians, physicists, statisticians, computers scientists. Everybody is welcome to participate! Please send us an email if you wish to participate.

For more information and contact details see the website (under construction).

This summer school is made possible with funding from the Australian Mathematical Science Institute (AMSI).
