RFV discussion: December 2016–May 2017
Created by an anon today. I searched that codepoint using Google and Google Books, and I looked on Wikipedia, but I don't know what it means. Current definition: "Ring in equal to." It should be replaced by a definition about actual usage if applicable, like maybe "Indicates equality in the context X". --Daniel Carrero (talk) 17:51, 15 December 2016 (UTC)


 * The meaning of the symbol (one meaning, anyway) is explained on page 5 of http://people.cs.uchicago.edu/~razborov/files/free_group.pdf. It is highly technical, and I don't personally understand it. I could copy-paste together a definition like "In combinatorial group theory, denotes graphical (or letter-for-letter) equality", but really we need a mathematician.

 * The other issue is if this definition is widely accepted among group theorists or whether it was just made up for this paper. DTLHS (talk) 20:34, 15 December 2016 (UTC)


 * Per WT:CFI, I'm pretty sure we would be satisfied if three separate, independent papers use this symbol. --Daniel Carrero (talk) 20:41, 15 December 2016 (UTC)


 * This book seems to use the same symbol with the same meaning. From a bit of searching, some other books use other symbols, such as ≡ or ≐. Pinging User:Msh210 and User:Kephir, who I think know more math than I do. —Granger (talk · contribs) 01:30, 16 December 2016 (UTC)


 * Found another instance in this paper. — justin(r)leung { (t...) 01:51, 16 December 2016 (UTC)


 * It seems to be used for other things, like in this (relation of delimitation) and this (Boolean equality). On another note, it is often used in kaomoji to represent narrow eyes. — justin(r)leung { (t...) 02:07, 16 December 2016 (UTC)


 * Have you considered asking Wikipedia:en:WT:MATHEMATICS ? -- 65.94.168.229 05:29, 17 December 2016 (UTC)


 * Ok. See w:Wikipedia talk:WikiProject Mathematics. --Daniel Carrero (talk) 22:26, 22 December 2016 (UTC)
 * For future reference, that discussion has been archived to w:Wikipedia talk:WikiProject Mathematics/Archive/2016/Dec. I have added a definition based on it. —Μετάknowledge discuss/deeds 19:27, 11 May 2017 (UTC)


 * RFV passed. —Μετάknowledge discuss/deeds 19:27, 11 May 2017 (UTC)
