Local formulas for multiplicative forms

Alejandro Cabrera, Ioan Marcut, Maria Amelia Salazar

摘要:

我们提供了明确的公式积分乘法形式的局部李群胚的无穷小数据。结合我们以前的工作[8],它构造了李代数胚的局部李群胚,这些公式产生了几个无穷小定义的几何结构的具体积分。特别是,我们得到的局部积分和非退化实现的泊松,Nijenhuis-Poisson,狄拉克和Jacobi结构的局部辛,辛Nijenhuis,前辛,接触群胚,分别。

英文摘要:

We provide explicit formulas for integrating multiplicative forms on local Lie groupoids in terms of infinitesimal data. Combined with our previous work [8], which constructs the local Lie groupoid of a Lie algebroid, these formulas produce concrete integrations of several geometric stuctures defined infinitesimally. In particular, we obtain local integrations and non-degenerate realizations of Poisson, Nijenhuis-Poisson, Dirac, and Jacobi structures by local symplectic, symplectic-Nijenhuis, presymplectic, and contact groupoids, respectively.
