Triangulation of cw complex
A CW complex (also called cellular complex or cell complex) is a kind of a topological space that is particularly important in algebraic topology. It was introduced by J. H. C. Whitehead to meet the needs of homotopy theory. This class of spaces is broader and has some better categorical properties than simplicial … See more CW complex A CW complex is constructed by taking the union of a sequence of topological spaces Each $${\displaystyle X_{k}}$$ is called the k-skeleton of the complex. The topology of See more • CW complexes are locally contractible (Hatcher, prop. A.4). • If a space is homotopic to a CW complex, then it has a good open cover. A good open cover is an open cover, such … See more There is a technique, developed by Whitehead, for replacing a CW complex with a homotopy-equivalent CW complex that has a simpler … See more • Abstract cell complex • The notion of CW complex has an adaptation to smooth manifolds called a handle decomposition, which is closely related to surgery theory. See more 0-dimensional CW complexes Every discrete topological space is a 0-dimensional CW complex. 1-dimensional CW complexes Some examples of 1-dimensional CW complexes are: • An … See more Singular homology and cohomology of CW complexes is readily computable via cellular homology. Moreover, in the category of CW … See more The homotopy category of CW complexes is, in the opinion of some experts, the best if not the only candidate for the homotopy category (for … See more WebPerformance is clearly improvable. The complexity inceases exponentially with the number of holes. Using some kind of binary partitioning (BSP-Tree, Octree) would speed up the algorithm dramatically. Notes. Polygons have to be specified in counter clockwise orientation. Each point of the polygon has to lie on the same plane.

WebIn this paper, the interconnection between the cohomology of measured group actions and the cohomology of measured laminations is explored, the latter being a generalization of the former for the case of discrete group actions and cocycles evaluated on abelian groups. This relation gives a rich interplay between these concepts. Several results can be …
