Improved formatting, added explanation
Apr 21, 2010 at 9:30 comment added Charles Stewart I understand that the theorem is due to Spector (1956) On degrees of recursive unsolvability, Annals of Mathematics 64:581-592. It's a very nice theorem: Shore stresses its use in eliminating second-order quantification.
Apr 21, 2010 at 4:40 comment added Andrej Bauer I don't have much to say here, except that the poset $P = \mathbb{N} \cup \lbrace\infty_1,\infty_2\rbrace$ with the usual ordering on the natural numbers and the additional stipulations $n \leq \infty_1$, $n \leq \infty_2$ often serves as a counter-example in domain theory.
