给定一个李代数胚,讨论其阿贝尔化的光滑阿贝尔积分的存在性。我们表明,障碍有关的扩展单值群最近介绍。我们还表明,这个广群可以通过一个路径空间的建设,类似的温斯坦广群,但在基础同伦现在支持的表面与任意属。作为一个应用,我们证明了(可能非单连通)流形的预量子化条件等价于阿贝尔积分的光滑性。我们的结果可以解释为经典Hurewicz定理的推广。
Given a Lie algebroid we discuss the existence of a smooth abelian integration of its abelianization. We show that the obstructions are related to the extended monodromy groups introduced recently in . We also show that this groupoid can be obtained by a path-space construction, similar to the Weinstein groupoid of , but where the underlying homotopies are now supported in surfaces with arbitrary genus. As an application, we show that the prequantization condition for a (possibly non-simply connected) manifold is equivalent to the smoothness of an abelian integration. Our results can be interpreted as a generalization of the classical Hurewicz theorem.
