叶李代数胚与Courant代数胚

Foliated Lie and Courant Algebroids

Izu Vaisman

摘要:

如果$A$是一个有叶流形$(M,\mathcal{F})$上的李代数胚,则$A$的一个有叶流形是一个具有锚象$T\mathcal{F}$的李子代数胚$B$,并且使得$A/B$与$\mathcal{F}$的切片流形上的李代数胚局部等价。我们给出了几个例子,对于叶理李代数胚,我们讨论了以下主题:对偶Poisson结构和Vaintrob的超向量场、叶理的上同调和变形、对李群胚的积分。在最后一节中,我们定义了一个对应的概念,一个柯朗代数胚$A$作为一个括号封闭,迷向子丛$B$锚形象$T\mathcal{F}$,并使$B^\perp/B$是局部等价的柯朗代数胚在切片流形$\mathcal{F}$。给出了激发定义的例子。

英文摘要:

If $A$ is a Lie algebroid over a foliated manifold $(M,\mathcal{F})$, a foliation of $A$ is a Lie subalgebroid $B$ with anchor image $T\mathcal{F}$ and such that $A/B$ is locally equivalent with Lie algebroids over the slice manifolds of $\mathcal{F}$. We give several examples and, for foliated Lie algebroids, we discuss the following subjects: the dual Poisson structure and Vaintrob's super-vector field, cohomology and deformations of the foliation, integration to a Lie groupoid. In the last section, we define a corresponding notion of a foliation of a Courant algebroid $A$ as a bracket-closed, isotropic subbundle $B$ with anchor image $T\mathcal{F}$ and such that $B^\perp/B$ is locally equivalent with Courant algebroids over the slice manifolds of $\mathcal{F}$. Examples that motivate the definition are given.
