- This is in Shoenfield's book, "Mathematical Logic," page 87.
- Shoenfield gives a model-theoretic proof that the theory of the
- real ordered field admits elimination of quantifiers. The
- result is due to Tarski (about 1939, but not published until
- after the war). There is more recent work on upper and lower
- bounds on the complexity of implementation of the decision
- procedure one gets from all this.
