Smooth Differential Formsth manifold .. In this section we review the construction of ..(.) and establish a chain of quasi-isomorphisms . of commutative cochain algebras. This implies (§12) that ..(.) and ..(.; ?) have the same minimal Sullivan algebras and hence that many rational homotopy invariants (e.g. dim π.(.) ? ?, .

Relative Sullivan algebrasic morphism k → (., .), 1→ 1. In this section we introduce relative Sullivan algebras (. ? Λ.,.) and use them to model general morphisms (...) → (.,.) of commutative cochain algebras. We shall then prove existence and uniqueness theorems in this setting. This will, in particular, eliminate the hypot
