Günther, Bernd The use of semisimplicial complexes in strong shape theory. (English) Zbl 0781.55006 Glas. Mat., III. Ser. 27, No. 1, 101-144 (1992). Amongst the known descriptions of strong shape theory, one due to F. W. Bauer [The advantages of strong shape theory, in “Topology, general and algebraic topology, and applications”, Proc. Int. Conf., Leningrad 1982, Lect. Notes Math. 1060, 119-128 (1984; Zbl 0553.55007)] uses the language of \(\infty\)-categories. The author here puts forward an approach based on simplicial enriched categories, and homotopy coherence using various ideas from the work of R. M. Vogt [Math. Z. 134, 11-52 (1973; Zbl 0276.55006)] and J.-M. Cordier and the reviewer [Math. Proc. Camb. Philos. Soc. 100, 65-90 (1986; Zbl 0603.55017)]. Using large simplicial sets, he constructs for each space a simplicial analogue of a comma category of ‘nice spaces’ under \(X\). He then uses these to define the strong shape theory category and a strong shape category of pairs.
