Wikipedia:Articles for deletion/Duality (mathematics)
This is a  if ever there was one.  If the article is crappy, it should be fixed.  The stated reason for deletion, "I have never seen the word "dual" or the concept of duality itself defined or discussed in mathematical literature" is a phenomenal admission of both ignorance and indolence, as ''any'' trivial web or literature search would have turned up dozens of examples.  (http://www.google.com/search?q=site%3Amathworld.wolfram.com+dual Search for "dual" on MathWorld.)  I would hope that nominator recognizes that this nomination was a serious mistake
