一个辛类群g:= (G1 G0)决定了G0上的泊松结构。在这种情况下,我们称g为泊松流形G0的辛群。然而,并不是每个泊松流形都有这样的辛群。这使我们远离了一些理想的目标:例如,在所有泊松流形的范畴中建立森田等价。本文构造了一个辛Weinstein群,它提供了上述问题的一个解(定理1.1)。更确切地说,我们证明了一个辛Weinstein群在它的基流形上诱导出一个泊松结构,并且每个泊松流形都有一个相关联的辛Weinstein群。
A symplectic groupoid G. := (G1 G0) determines a Poisson structure on G0. In this case, we call G. a symplectic groupoid of the Poisson manifold G0. However, not every Poisson manifold has such a symplectic groupoid. This keeps us away from some desirable goals: For example, establishing Morita equivalence in the category of all Poisson manifolds. In this paper, we construct symplectic Weinstein groupoids which provide a solution to the above problem (Theorem 1.1). More precisely, we show that a symplectic Weinstein groupoid induces a Poisson structure on its base manifold, and that to every Poisson manifold there is an associated symplectic Weinstein groupoid.
