CW Complex

In topology, a CW complex is a type of topological space 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 complexes, but still retains a combinatorial nature that allows for computation (often with a much smaller complex).

Famous quotes containing the word complex:

    By “object” is meant some element in the complex whole that is defined in abstraction from the whole of which it is a distinction.
    John Dewey (1859–1952)
