| 摘 要： | For a transitive Lie algebroid A on a connected manifold M and its representation on a vector bundle F, we define a morphism of cohomology groups rk: Hk(A,F) → Hk(Lx,Fx), called the localization map, where Lx is the adjoint algebra at x ∈ M. The main result in this paper is that if M is simply connected, or H (LX,FX) is trivial, then T is injective. This means that the Lie algebroid 1-cohomology is totally determined by the 1-cohomology of its adjoint Lie algebra in the above two cases.

| Abstract: | For a transitive Lie algebroid A on a connected manifold M and its representation on a vector bundle F, we define a morphism of cohomology groups ϒ?κ: H
κ(A, F) → H
κ(L
χ, F
χ), called the localization map, where L
χ is the adjoint algebra at χ ∈ M. The main result in this paper is that if M is simply connected, or H0(L
χ, F
χ) is trivial, then ϒ1 is injective. This means that the Lie algebroid 1-cohomology is totally determined by the 1-cohomology of its adjoint Lie
algebra in the above two cases. |
