Algebraic Topology Discussion List: - The primary functions of this list are: providing abstracts of papers posted to the Hopf archive, providing information about topology conferences, and serving as a forum for topics related to algebraic topology. The site also serves as an archive of links to websites related to algebraic topology.
British Topology Home Page: - A source of pointers to Topology-related sites, including archives and conference announcements.
The Cantor Set: - Article in the Platonic Realms, describing the Cantor discontinuum, a favorite example of topology. Includes examples and illustrations.
Differential Topology: - Course notes by Matthew G. Brin in PostScript including "Introduction to Differential Topology", "Introduction to Seifert fibered 3-manifolds", "Groups acting on 1-dimensional spaces", and "Presentations, conjugacy, roots and centralizers in groups of piecewise linear homeomorphisms of the real line".
TTT on WWW: - The Transpennine Topology Triangle is a topology seminar partially supported by the London Mathematical Society with vertices at Leicester, Manchester and Sheffield.
What is Topology?: - An introductory essay by Neil Strickland, University of Sheffield.
