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:

Monotonically normal space (DEFINITION): Like a normal space, except that the open subsets separating closed subsets should vary monotonically.

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

Proving compactness (SURVEY ARTICLE): Ever thought of how to prove a topological space is compact? Read about it.
