微分分次接触几何与Jacobi结构

Differential graded contact geometry and Jacobi structures

Rajan Amit Mehta

摘要:

研究了具有同调切触向量场的非负分次流形上的切触结构。在度1的情况下,我们表明,有一个一对一的对应关系,这样的结构(与固定接触形式)和雅可比流形。这种对应关系使我们能够重新解释泊松化过程,将雅可比流形变为泊松流形,作为辛化的超几何版本。

英文摘要:

We study contact structures on nonnegatively-graded manifolds equipped with homological contact vector fields. In the degree 1 case, we show that there is a one-to-one correspondence between such structures (with fixed contact form) and Jacobi manifolds. This correspondence allows us to reinterpret the Poissonization procedure, taking Jacobi manifolds to Poisson manifolds, as a supergeometric version of symplectization.
