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.

Gandalf is the pure maths student seminar. Gandalf stands for the Geometry AND ALgebra Forum. It is run by and for pure postgraduates, but welcomes anyone who is interested in coming along.
