Many categories have been used to model concurrency. Using any of these, thechallenge is to reduce a given model to a smaller representation whichnevertheless preserves the relevant computer-scientific information. That is,one wants to replace a given model with a simpler model with the same directedhomotopy-type. Unfortunately, the obvious definition of directed homotopyequivalence is too coarse. This paper introduces the notion of context torefine this definition.Comment: 18 pages, to appear in Electronic Notes in Theoretical Computer Science, preliminary version in Proceedings of the Workshop on Geometry and Topology in Concurrency and Distributed Computing, BRICS Notes NS-04-2, pp.33-4
