Existential 0-definability of henselian valuation rings

Published 8 Jul 2013 in math.AC and math.LO | (1307.1956v2)

Abstract: Recently, Anscombe and Koenigsmann gave an existential 0-definition of the ring of formal power series F[[t]] in its quotient field in the case where F is finite. We extend their method in several directions to give general definability results for henselian valued fields with finite or pseudo-algebraically closed residue fields.
