Functorality,space C and for any simplicial complex X, the map from homotopy classes of maps from X to C to the homotopy classes of maps from the minimal model of the p.l. forms on C to that for X is a functorial bijection. We reformulate this result as an equivalence of the rational homotopy category of simplycollagenase 发表于 2025-3-25 11:15:27

,,-Structures and ,,-Structures, then state the result that homotopy theory of commutative DGAs is equivalent to the homotopy theory of commutative A-infinity algebras, the so-called C-infinity algebras. It follows that there is a C-infinity map from the cohomology of a space to its minimal model, a map which induces the identity头盔 发表于 2025-3-25 16:25:34

DGAs and Rational Homotopy Theory,stablished, inductively one shows that the rational Postnikov tower of a space is read off from the minimal model of the p.l. forms on the space. The proof of the main inductive result, the Hirsch lemma, is postponed until Chap. .打火石 发表于 2025-3-26 02:05:42
,Eilenberg–MacLane Spaces, Cohomology, and Principal Fibrations,This chapter begins by showing that maps of a CW complex to an Eilenberg–MacLane space are classified by the elements in a cohomology group. Then principal fibrations with fiber an Eilenberg–MacLane space are classified by elements in a similar cohomology group.Cougar 发表于 2025-3-26 05:14:58
The Hirsch Lemma,In this chapter, we prove the main technical result from Chap. ., namely, the result comparing principle bundles and Hirsch extensions.首创精神 发表于 2025-3-26 11:23:53
