An example of a $P$-minimal structure without definable Skolem functions

Logic 2018-03-22 v2 Number Theory

Abstract

We show there are intermediate PP-minimal structures between the semi-algebraic and sub-analytic languages which do not have definable Skolem functions. As a consequence, by a result of Mourgues, this shows there are PP-minimal structures which do not admit classical cell decomposition.
