C. Duval, A. M. El Gradechi, V. Ovsienko

摘要:

本文考虑T^*M上光滑函数的Poisson代数S(M)是纤维多项式.在M是局部投影的情况下(分别为保形)平坦的,我们寻找S(M)上的星积SL(n+1,R)(分别为. SO(p+1,q+1))-不变。我们证明了存在这样的星产品使用射影(分别)。保形)等变量子化,证明了它们的唯一性,并研究了它们的主要性质。最后给出了标准射影不变星积的一个显式公式。

英文摘要:

We consider the Poisson algebra S(M) of smooth functions on T^*M which are fiberwise polynomial. In the case where M is locally projectively (resp. conformally) flat, we seek the star-products on S(M) which are SL(n+1,R) (resp. SO(p+1,q+1))-invariant. We prove the existence of such star-products using the projectively (resp. conformally) equivariant quantization, then prove their uniqueness, and study their main properties. We finally give an explicit formula for the canonical projectively invariant star-product.
