Talk:Boris Tsirelson

Interwiki link

I see the corresponding article in German: [1], but fail to make an interwiki link to it from here. Boris Tsirelson (talk) 13:27, 21 July 2014 (UTC)

Without explaining his reasons

"Tsirelson is known for undoing other people's Wikiedia edits without explaining his reasons for doing so." This phrase is added by User:Daqu just after he "Added the fact that this Cantor set is homeomorphic to the middle-thirds Cantor set" to "Smith–Volterra–Cantor set", and I thanked him for this addition and added wikilink to "Homeomorphism" to his words "topologically equivalent". Very puzzling. I was never so much puzzled by another wikipedian. I would be glad to see his reason explained. Boris Tsirelson (talk) 06:23, 14 December 2014 (UTC)

Now I am looking at my "Contributions": maybe I forgot some undoing? The last undoing by me was on Dec 2, "Topological space", with edit summary "not an "interesting question"; just (4) above; and anyway, ask questions on the talk page, not here." Did not I explain my reason? Is "176.92.153.87" another name of Daqu? Highly puzzling. Boris Tsirelson (talk) 06:29, 14 December 2014 (UTC)

(But wait for reliable source, of course.). Happy editing (and ultimately, happy exiting, if you like). Boris Tsirelson (talk) 20:54, 20 January 2020 (UTC)

For those edit warring on this article: please respect the last wishes of Boris Tsirelson, and wait for reliable sources. His talk page is not one. Tercer (talk) 12:00, 23 February 2020 (UTC)

Sadly, this is now confirmed by a RS (with the article appropriately updated). --JBL (talk) 16:56, 26 February 2020 (UTC)
