Model categories for o-minimal geometry

Algebraic Topology 2021-08-27 v1 Category Theory Logic

Abstract

We introduce a model category of spaces based on the definable sets of an o-minimal expansion of a real closed field. As a model category, it resembles the category of topological spaces, but its underlying category is a coherent topos. We will show in future work that its cofibrant objects are precisely the "weak polytopes" of Knebusch.
