3 - Open and closed sets

Описание к видео 3 - Open and closed sets

This video continues the series, discussing open and closed sets, interiors and closure, and dense sets and separability of metric spaces. It follows the seventh page of my course handouts, corresponding to Chapter 4 in Carothers.

This video moves quickly (and has a lot of content)! Please rewind, rewatch, and/or slow the playback speed as necessary---once the whole thing makes sense in real time, you're in pretty good shape with the basic concepts!
