A fundamental dichotomy for definably complete expansions of ordered fields

Logic 2016-01-19 v2

Abstract

An expansion of a definably complete field either defines a discrete subring, or the image of a definable discrete set under a definable map is nowhere dense. As an application we show a definable version of Lebesgue's differentiation theorem.
