Comment[edit]
I realize this is marked as under construction, but low-dimensional topology seems badly underrepresented here. In particular the 2d uniformization theorem (conjectured 1892–3 by Poincaré and Klein and proved 1907 by Poincaré and Koebe), the 3d geometrization conjecture (conjectured 1982 by Thurston and proved 2003 by Perelman), Haken manifolds (introduced 1961) and the Virtually Haken conjecture are all conspicuous by their absence here. —David Eppstein (talk) 06:04, 16 December 2017 (UTC)
- Indeed. I intend to make improvements. The original draft by Andrew Ranicki was clearly overtaken by the timeline for algebraic topology, and was abandoned. Charles Matthews (talk) 14:06, 2 January 2018 (UTC)
4-dimensional topological Poincaré conjecture?[edit]
I hope someone knowledgeable about the subject will include Michael Freedman's proof of the 4-dimensional topological Poincaré conjecture among the crowning achievements in the history of manifolds.
Some of the current listings seem much, much, much less central to topology than that proof, yet it is omitted. Why?
