Introductory section
Hello. In the article titled Frink ideal, you began with this:
 * LU(A) is the set of all lower bounds of the set of all upper bounds of the subset A of a partially ordered set.
 * LU(A) is the set of all lower bounds of the set of all upper bounds of the subset A of a partially ordered set.

After reading that sentence, the lay reader does not know whether the article is about or whatever.
 * jurisprudence, or
 * chemistry, or
 * moral philosophy, or
 * a card game, or
 * theory of banking, or
 * the manufacture of electronic music synthesizers, or
 * air traffic scheduling and control, or
 * baseball statistics

So I added an introductory section. It's only a terse sentence, and it can probably be improved. Michael Hardy (talk) 04:34, 5 March 2009 (UTC)
