Fixed semi-base[edit]

The semi-base didn't include both intervals [0 x) and (x 1]; I added them. (talk) 19:34, 27 December 2011 (UTC)

Thanks for your recent changes. As far as I can see, they seem to disagree with the Steen, L. A.; Seebach, J. A. (1995), Counterexamples in Topology, Dover, p. 3, ISBN 048668735X . If you want to alter the definition then it's a good idea to add a reference (see wp:v and wp:rs). Fly by Night (talk) 20:07, 27 December 2011 (UTC)


I changed this page to be similar to Long line. I deleted the definition of the order topology (it was wrong, what was presented was the Right order topology). I added a Properties section summarizing relevant properties.Mennucc (talk) 16:54, 14 July 2014 (UTC)
