Gandalf (Pure Maths Student Seminar): Riemann Existence Theorem I: Fundamental groups of the punctured Riemann sphere

Presented by John Mcleod, Durham

25 January 2012 16:15 in CM107

We open this term with a couple of seminars on the Riemann Existence Theorem, which states the connection between the punctured Riemann sphere and Fuchsian groups. Along the way we will touch on a bit of Topology, a dash of algebraic geometry, and a smidgeon of group theory. The RET is an important ingredient in an approach to the Inverse Galois problem. By the end of the second seminar, we hope to have proven a lesser result, the Profinite Riemann Existence Theorem.
