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...

Look up CW in Wiktionary, the free dictionary. CW may stand for: centiwatt (cW), one hundredth of a watt Cω, a programming language CW complex, a type...

contravariant functor F on the homotopy category Hotc of pointed connected CW complexes, to the category of sets Set, to be a representable functor. More specifically...

minimal regular CW structure on the sphere. In light of the smooth structure, the existence of a Morse function would show RPn is a CW complex. One such function...

{\displaystyle n} -cells. Each simplicial complex is a CW-complex, the inverse is not true. The construction of CW-complexes can be used to define cellular homology...

Every ANR has the homotopy type of a very simple topological space, a CW complex. Let X be a topological space and A a subspace of X. Then a continuous...

equivalence from a CW complex, this axiom reduces homology or cohomology theories on all spaces to the corresponding theory on CW complexes. Some examples...

Moreover, it is common to assume that this space is a CW-complex (which is always possible via CW approximation). The name is derived from Samuel Eilenberg...

Simplicial complex, a kind of topological space CW complex, a kind of topological space Line complex, a 3-dimensional family of lines in space Complex (geology)...

line with a single point removed. Real projective spaces have a simple CW complex structure, as Pn(R) can be obtained from Pn−1(R) by attaching an n-cell...
