Computing homotopy types using crossed n-cubes of groups

Abstract:

This paper is a slightly edited version in {\small \LaTeX\ } of the paper of the same title which appeared in the {\em Adams Memorial Symposium on Algebraic Topology}, Vol 1, edited N. Ray and G Walker, Cambridge University Press, 1992, 187-210. It gives a survey of some computational uses in homotopy theory of various structures related to multiple groupoids.

Cubical groups which are Kan

Abstract:

The category of cubical sets with connections of Brown and Higgins is introduced as a possible alternative to simplicial complexes for carrying out a programme of combinatorial homotopy theory. This paper provides a result crucial to the development of this theory, that group objects in the category of cubical sets with connections have the property of being Kan.
