Seminar Archive - 2012

Our regular seminar program covers a broad range of topics from applied mathematics, pure mathematics and statistics. All staff and students are welcome. A complete list of past seminars can be accessed via the left-hand menu.

Roozbeh Hazrat - University of Western Sydney
This talk is about graphs and algebras. We start with a graph and build an algebra out of it. Then we ask if we change a graph, what will happen to the algebra. We show that the algebra constructed...

Susan Friedlander - University of Southern California
We discuss an advection-diffusion equation that has been proposed by Keith Moffatt as a model for the Geodynamo. Even though the drift velocity can be strongly singular, we prove that the critically...

Michael Joswig - Technische Universität Darmstadt
It is a key observation, made by Kapranov, Mikhalkin, Sturmfels, and others, that relevant geometric problems have acombinatorial core. This lead to the invention of tropical geometry as something...

Timothy Trudgian - Australian National University
One could prove the Riemann hypothesis if one could show that some certain arithmetical sums are of a constant sign. Two such sums, studied by Pólya and Turán, are known not to be of a constant...

Kang Zuo - Johannes Gutenberg University of Mainz
My lecture is based on a recent joint paper with G-T. Lan and M. Sheng.Let $k$ be an algebraic closure of finite fields with odd characteristic $p$ and a smooth projective scheme $\mathbf{X}/W(k)$....
