Talk:Epsilon

message: From introduction section "The lunate epsilon ϵ is not to be confused with the set symbol ∈."  However the Symbol section states "In mathematics, set membership (often written ∈ instead of ε)."  I believe that the latter definition should be deleted.  The set symbol is NOT an epsilon, it is just a generic mathematical symbol. 220.233.204.250 05:42, 4 August 2007 (UTC)

thread_title:  Epsilon 

message: Rather than the Greek epsilon being favored, and with as many other things (companies, languages, etc.) known simply as "Epsilon", having them all routed through this article doesn't make much sense. With "Epsilon" being a significant news item, it shouldn't be this difficult to discover that nobody has created an entry for the company yet. Merennulli (talk) 17:06, 4 April 2011 (UTC)

message: , sorry, I don't understand your . The text (you removed) said nothing about Halmos, only about modern usage. (1) Nowadays, we write x∈X or x∊X to denote that x is element if X; (2) The ∈ (∊) sign derives from Greek epsilon (specifically from its lunate form). Are there any doubts?

replies: text: The main issue was that the Halmos text was being used as a source of a statement that it didn't support.  There are a lot of formatting errors too, but those are fixable.  In any case, if it's mainly a statement about the "element of" symbol, then it's not so much about the letter epsilon itself. –Deacon Vorbis (carbon • videos) 19:48, 18 September 2020 (UTC)
replies: text:  , ”the main issue was that the Halmos text was being used” — I am sorry, but what Halmos text are you talking about? There is no reference to any Halmos text in my proposed change. And I consider the statement about the "element of" symbol to be very related, because the "element of" symbol derives from epsilon. Sasha1024 (talk) 13:03, 22 October 2020 (UTC)
replies: text: Apparently someone else added a source to your addition.  The source that was added didn't support what you wrote, which was unsourced, so it would need a source to be added at all. –Deacon Vorbis (carbon • videos) 13:21, 22 October 2020 (UTC)
replies: text:  Source for what exactly: for (a) the fact that ∈ (or ∊) is nowadays used as "is element of" or for (b) the fact that nowaday ∈ (and ∊) derives from lunate epsilon? (I thought both are obvious, but maybe can provide sources for both of them.) (BTW, did you notice that no entries in that list contain sources?) Sasha1024 (talk) 10:49, 23 October 2020 (UTC)
