关于向量丛的一个李代数特征

On a Lie Algebraic Characterization of Vector Bundles

Pierre B. A. Lecomte, Thomas Leuther, Elie Zihindula Mushengezi

摘要:

证明了向量丛$π: E \to M$是由$E$上的所有微分算子生成的李代数所刻画的,这些微分算子是欧拉向量场方向上的李导数的特征向量.我们的结果是Pursell-Shanks型的,但它是值得注意的,因为它是整个纤维化的特点在这里。证明依赖于[Lecomte P.,J.Math.PuresAppl.(9)60(1981),229-239],并继承了相同的假设。特别是,我们的特征仅适用于秩大于1的向量丛。

英文摘要:

We prove that a vector bundle $π: E \to M$ is characterized by the Lie algebra generated by all differential operators on $E$ which are eigenvectors of the Lie derivative in the direction of the Euler vector field. Our result is of Pursell-Shanks type but it is remarkable in the sense that it is the whole fibration that is characterized here. The proof relies on a theorem of [Lecomte P., J. Math. Pures Appl. (9) 60 (1981), 229-239] and inherits the same hypotheses. In particular, our characterization holds only for vector bundles of rank greater than 1.
