Web9 Nov 2024 · 4. By a good closed cover of a topological space X, I mean a collection of closed subspaces of X, such that the interior of them cover X, and any finite intersection of these closed subspaces is contractible. Every triangulable space X admits a good open cover: just fix a triangulation and take open stars at all vertices. WebShow that the second barycentric subdivision of a $\Delta$ -complex is a simplicial complex. Namely, show that the first barycentric subdivision produces a $\Delta$ -complex with the property that each simplex has all its vertices distinct, then show that for a \Delta-complex with this property, barycentric subdivision produces a simplicial complex.
