From Topospaces

Welcome toTopospaces (The Topology Wiki). This is a pre-alpha stage topology wiki primarily managed by Vipul Naik, a Ph.D. student in Mathematics at the University of Chicago. We have over 400 articles including some material in basic point-set topology. It is part of a broader subject wikis initiative -- see the subject wikis reference guide for more details

Suggested articles:

Simple space (DEFINITION): A path-connected space whose fundamental group is Abelian and acts trivially on all the higher homotopy groups.

Three sides lemma (FACT): The inclusion of three sides of a square, in the filled square, is just like the inclusion of one side.

Applying compactness (SURVEY ARTICLE): Explore how the fact that a topological space is compact can be put to good use.
