Uniform Definability of Henselian Valuation Rings in the Macintyre
Erschienen in: Bulletin of the London Mathematical Society ; 47 (2015), 4. - S. 693-703 https://dx.doi.org/10.1112/blms/bdv042 Uniform definability of henselian valuation rings in the Macintyre language Arno Fehm and Alexander Prestel Abstract We discuss definability of henselian valuation rings in the Macintyre language LMac, the language of rings expanded by nth power predicates. In particular, we show that henselian valuation rings with finite or Hilbertian residue field are uniformly ∃-∅-definable in LMac, and henselian valuation rings with value group Z are uniformly ∃∀-∅-definable in the ring language, but not uniformly ∃-∅-definable in LMac. We apply these results to local fields Qp and Fp((t)), as well as to higher dimensional local fields. 1. Introduction The question of definability of henselian valuation rings in their quotient fields goes back at least to Julia Robinson, who observed that the ring of p-adic integers Zp can be characterized inside the field of p-adic numbers Qp purely algebraically, for example, for odd prime numbers p as 2 2 Zp = {x ∈ Qp :(∃y ∈ Qp)(y =1+px )}. This definition of the henselian valuation ring of the local field Qp is existential (or diophantine) and parameter-free (∃-∅, for short), and it depends on p. For the local fields Fp((t)), an existential parameter-free definition of the henselian valuation ring Fp[[t]] is much less obvious and was given only recently in [1]. Also this definition depends heavily on p. Of particular importance in this subject and in applications to diophantine geometry and the model theory of fields is the question whether there are uniform definitions, for example, of Zp in Qp independent of p, and how complex such definitions have to be. -
