Poisson群作用的可积性与约化

Integrability and reduction of Poisson group actions

Luca Stefanini

摘要:

本文研究了完全Poisson群的Poisson作用,不需要任何连通性假设,也不需要动量映射的存在。对任何具有对偶$G^\star$的完全Poisson群$G$,我们得到了一个适当连通的积分辛对偶广群$\calS$ .因此,可积泊松流形$P$上的泊松作用的余切提升可以积分为$P$的辛群胚$\poidd{\calS}{G^\star}$在辛群胚上的泊松作用。最后,我们证明了商泊松流形$P/G$也是可积的,给出了一个明确的辛群胚的建设,通过减少程序的相关态射的双重李群胚。

英文摘要:

In this paper we study Poisson actions of complete Poisson groups, without any connectivity assumption or requiring the existence of a momentum map. For any complete Poisson group $G$ with dual $G^\star$ we obtain a suitably connected integrating symplectic double groupoid $\calS$. As a consequence, the cotangent lift of a Poisson action on an integrable Poisson manifold $P$ can be integrated to a Poisson action of the symplectic groupoid $\poidd{\calS}{G^\star}$ on the symplectic groupoid for $P$. Finally, we show that the quotient Poisson manifold $P/G$ is also integrable, giving an explicit construction of a symplectic groupoid for it, by a reduction procedure on an associated morphism of double Lie groupoids.
