Citation needed for origin of name[edit]

Personally, I'd mark "probabilistic metric spaces t-norms are used to generalize triangle inequality of ordinary metric spaces." with a "citation needed" because I have not yet read this despite having looked in multiple books about Fuzzy logic. To be precise: There is a general agreement that t means triangular but the explanation that it is called triangular norm because it generalized the triangle equality is not something I was readily able to find. Maybe someone can provide a reference for this claim? — Preceding unsigned comment added by (talk) 08:54, 13 June 2017 (UTC)

The title does not represent the containts[edit]

I think t-norm and t-conorm should be in different articles or the title of this article should be different and include other fuzzy logic operations as negation. Your thoughts? --trylks 21:43, 15 September 2007 (UTC)

I have put t-conorms in the same article as t-norms since the former are just duals of the latter, and I did not plan to write much more on t-conorms myself; so it seemed to me that a separate article would at present just repeat (or dualize) the contents of the article on t-norms. However, if anybody thinks that t-conorms (or residua) deserve a separate article and that there is enough material for one, I am not going to oppose. I suppose that in the long run, many other fuzzy-logic operators would deserve their own articles as well. I wrote only on t-norms (and their derivative operators) since they are needed for t-norm based fuzzy logics like MTL, which were my primary aim. Any expansion of articles related to t-norms or other fuzzy-logic operators is of course very much welcome. -- LBehounek 18:44, 27 September 2007 (UTC)
