Internal categories as models of homotopy types
A homotopy n-type is a topological space which has trivial homotopy groups above degree n. Every space can be constructed from a sequence of such homotopy types, in a sense made precise by the theory of Postnikov towers, yielding improving `approximations' to the space by encoding information a...
