Urysohn's Metrization Theorem | A Survey
1. Prelude
Urysohn's Metrization theorem is one of the 'big boys' of second course in Topology. It works as an excellent survey problem that brings scattered ideas theorems and technical terms together.
We will examine a standard proof and review the terms and theorems used in the proof. While examining the various bits and pieces, we revisit the 'big picture' over and over again.
