Compression principle for cw complexes
WebOct 15, 2024 · Abstract: CW complexes are used extensively in algebraic topology, but the product of two CW complexes need not be a CW complex, as shown by Dowker. Whilst … Websimplicial complex. Its n-skeleton XnˆXis formed by keeping only the i-simplices for i n. Since there is a homeomorphism (n;@ n) ˘=(DnS 1), it is clear that Xis a nite cw-complex, with one n-cell for each n-simplex. Despite appearances, simplicial complexes include many spaces of interest.
