Defiing the integers in the rationals I
Abstract: In 1959 Julia Robinson showed that the ring of integers is definable in the
field of rational numbers. I will give a more conceptual proof due to Rumley.
This result is at the core of Scanlon's recent work on definabilty in finitely
generated fields.
