辛流形上直到等变Morita等价的不变星积的分类

Classification of Invariant Star Products up to Equivariant Morita Equivalence on Symplectic Manifolds

Stefan Jansen, Nikolai Neumaier, Gregor Schaumann, Stefan Waldmann

摘要:

本文研究了具有动量映射的代数的等变Morita理论,并利用Picard广群显式地计算了等变Picard广群。我们考虑三种类型的Morita理论:环理论等价,*-等价和强等价。然后,我们将这些一般的考虑应用到具有李代数对称性的辛流形上的星积代数。我们得到了完整的分类等变森田等价。

英文摘要:

In this paper we investigate equivariant Morita theory for algebras with momentum maps and compute the equivariant Picard groupoid in terms of the Picard groupoid explicitly. We consider three types of Morita theory: ring-theoretic equivalence, *-equivalence and strong equivalence. Then we apply these general considerations to star product algebras over symplectic manifolds with a Lie algebra symmetry. We obtain the full classification up to equivariant Morita equivalence.
