Closed subsets of a $\mathrm{CAT}(0)$ $2$–complex are intrinsically $\mathrm{CAT}(0)$

Russell Ricks

Algebraic & Geometric Topology 21 (2021) 1723–1744
Abstract

Let κ 0, and let X be a complete, locally finite CAT(κ) polyhedral 2–complex X, each face with constant curvature κ. Let E be a closed, rectifiably connected subset of X with trivial first singular homology. We show that E, under the induced path metric, is a complete CAT(κ) space.
