摘要

Let F →i E→p B be a fibration, ρ:F × ΩB → F the holonomy action of this fibration and e:ΩB → F the connecting map. It is shown that if the fibre F admits an H-structure v such that ρapprox= vo(1×e) (principal fibrations of all kinds satisfy such a condition), then i is a monomorphism if and only if it is weak monomorphism, the latter is equivalent to that Ωp has a homotopy right inverse Γ. If in addition Γ is an H-map, then ΩE has the same H-type as ΩB×ΩF.
