The Hrushovski Property for Compact Special Cube Complexes

General Topology 2024-04-02 v2

Abstract

We show that any compact nonpositively curved cube complex YY embeds in a compact nonpositively curved cube complex RR where each combinatorial injective partial local isometry of YY extends to an automorphism of RR. When YY is special and the collection of injective partial local isometries satisfies certain conditions, we show that RR can be chosen to be special and the embedding YRY\hookrightarrow R can be chosen to be a local isometry.
