2. Several other metrization theorems follow as simple corollaries to Urysohn's Theorem.
3. The Nagata Smirnov metrization theorem extends this to the non-separable case.
4. Moore spaces are generally interesting in mathematics because they may be applied to prove interesting metrization theorems.
5. I want to prove the following version of the Urysohn metrization theorem : A Hausdorff space is metrisable.

8. His name is attached to the Nagata Smirnov metrization theorem, which was proved independently by Nagata in 1950 and by Smirnov in 1951.
9. In one direction a compact Hausdorff space is a normal space and, by the Urysohn metrization theorem, second-countable then implies metrizable.
