Title: | Satake compactifications and metric Schottky problems |

Abstract: [ pdf ] |
The quotient of the Poincare upper half plane by the modular group SL(2,
Z) is a basic locally symmetric space and also the moduli space of
compact Riemann surfaces
of genus 1, and it admits two important classes of generalization:
- Moduli spaces M_g of compact Riemann surfaces of genus g>1,
- Arithmetic locally symmetric spaces \Gamma \ G/K such as the Siegel modular variety A_g, which is also the moduli of principally polarized abelian varieties of dimension g.
J: M_g --> A_g. In this talk, I will discuss some results along these lines related to the Stake compactifications and the Schottky problems on understanding the image J(M_g) in A_g from the metric perspective. (joint with topology seminar) |
