Opérations de Massey, la construction S et extensions de Yoneda. (Massey operations, S-construction and Yoneda extension). (French) Zbl 0569.55012
For any category \({\mathcal C}\) with cofibrations a simplicial set S\({\mathcal C}\) is constructed called the Waldhausen S-construction of \({\mathcal C}\). Here are defined the obstructions for S\({\mathcal C}\) to be a Kan simplicial set. For Quillen exact categories [D. Quillen, Lect. Notes Math. 341, 85-147 (1973; Zbl 0292.18004)] these obstructions are finer invariants than K-functors. Furthermore, they are connected to Massey- Yoneda operations through the generalization of an Adams construction [J. F. Adams, Topology 5, 21-71 (1966; Zbl 0145.199)].
