To mark the 200th anniversary of Bernhard Riemann's birth, his alma mater, the Georg August-Universität Göttingen, and the German Mathematical Society (DMV) organize the DMV Topic Day "Riemann's legacy". We discuss recent developments in some of the areas which Riemann has started and shaped.
Speakers:
- Valentin Blomer (Bonn)- Esther Cabezas Rivas (València)
- Gerhard Huisken (Tübingen)
- Jonathan Keating (Oxford)
- Hee Oh (Yale)
- David Rowe (Mainz)
Program:
The scientific program will start in the morning and will finish early afternoon.There will be the opportunity of contributions by registered participants in a poster session.
Lectures:
Jonathan Keating The zeta function post-RiemannI will discuss some of the things we have discovered about the zeta function since Riemann's death that I suspect he might have found interesting. In several cases, I will highlight connections with Physics.
Hee Oh Circles on the Riemann sphere: Dynamics and Rigidity
One of Bernhard Riemann’s great legacies is the geometric approach to complex analysis through Riemann surfaces. The simplest compact example is the Riemann sphere. Beautiful fractal configurations on this sphere, including Apollonian and Sierpiński-type circle packings, provide a bridge between classical geometry and modern dynamics. Starting from four natural questions about circle packings, I will show how viewing the Riemann sphere as the boundary at infinity of hyperbolic three-space leads directly into dynamics and rigidity in spaces of infinite volume.
