I'm using the amsthm package to layout theorems and their proofs. How can I reduce the vertical spacing between the last line of the theorem statement and the first line of the proof?
BTW, I tried achieving this by fiddling with the third parameter to
...but even negative values (as illustrated above) failed to bring the first line of the proof closer than a certain fixed distance of about 2.5 line heights.
A related question: how can I prevent pagebreaks between the theorem and the proof? I would like to ensure that at least two lines from the theorem statement precede the first line of a proof on a page. (One may fairly assume that there is no text interposed between the last line of the theorem statement and the first line of the proof.)
