Abstract

Lie algebroids, singular foliations, and Dirac structures are closely related objects. We examine the relation between their pullbacks under maps satisfying a constant rank or transversality assumption. A special case is given by blowdown maps. In that case, we also establish the relation between the blowup of a Lie algebroid and its singular foliation.

李代数、奇叶和狄拉克结构的回调和膨胀注解

李代数，奇叶和狄拉克结构是密切相关的对象。我们研究了在满足常秩或横向假设的映射下它们的回调之间的关系。排污图给出了一个特例。在这种情况下，我们也建立了李代数的爆破与其奇异叶理之间的关系。
