Complements of locally flat submanifolds are finite CW complexes

Bibliographic Details
Title: Complements of locally flat submanifolds are finite CW complexes
Authors: Ho, Andrew
Publication Year: 2024
Collection: Mathematics
Subject Terms: Mathematics - Geometric Topology, Mathematics - Algebraic Topology, 57N45, 57Q12
More Details: We show that if $Y$ is a compact topological manifold and $X$ is a locally flat submanifold, then the complement $Y - X$ is homotopy equivalent to a finite CW complex. This is a direct proof, and does not rely on much of the theory of topological manifolds.
