Gandalf (Pure Maths Student Seminar): Riemann Existence Theorem II: Profinite Groups
8 February 2012 16:15 in CM107An important part of the proof of the Riemann Existence Theorem involves the theory of Profinite Groups which are exactly those groups which arise from an inverse limit. We will delve a little deeper into the theory of inverse limits, starting from Category Theory and working up to the derivation of the p-adic numbers via an inverse limit.
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.
