WebOct 22, 2011 · This is the intuition that the nLab suggests. Now it is well-known that in ordinary category theory, a group is the same as a groupoid with one object. ... To give this construction, we will first describe the classifying space of a simplicial group. One incarnation of this is going to give the functor from simplicial groups to reduced ... WebOct 24, 2024 · The space B Z n = S ∞ / Z n is the classifying space for the cyclic group Z n. Here, S ∞ is understood to be a certain subset of the infinite dimensional Hilbert space C ∞ with the origin removed; the cyclic group is considered to act on it by multiplication with roots of unity. The unordered configuration space UConf n ( R 2) is the ... dolphin lodge worthing Web14. The standard classifying space functor B from topological groups to topological spaces is product preserving, so it takes abelian topological groups to abelian topological groups. Start with an abelian group G as a discrete topological group, so a K ( G, 0). Apply the functor B iteratively n times to reach B n G, which is an abelian ...
