局部环面流形与奇异Bohr-Sommerfeld叶

Locally toric manifolds and singular Bohr-Sommerfeld leaves

Mark D. Hamilton

摘要:

当几何量子化被应用到一个流形使用一个真正的偏振这是“足够好”,结果Sniatycki说,量化可以找到通过计数某些对象,称为玻尔-索末菲叶。随后,几位作者在研究不那么“漂亮”的流形的量子化时,将此作为计算玻尔-索末菲叶的动机。在本文中,我们研究的量子化的紧凑的辛流形,可以局部建模的复曲面流形,使用一个真正的偏振建模纤维的矩映射。我们直接计算的结果,并得到一个定理类似于Sniatycki的,它给出了量子化的计数玻尔-索末菲叶。然而,计数不包括玻尔-索末菲叶是单数。因此,获得的量化不同于使用Kaehler偏振获得的量化。

英文摘要:

When geometric quantization is applied to a manifold using a real polarization which is "nice enough", a result of Sniatycki says that the quantization can be found by counting certain objects, called Bohr-Sommerfeld leaves. Subsequently, several authors have taken this as motivation for counting Bohr-Sommerfeld leaves when studying the quantization of manifolds which are less "nice". In this paper, we examine the quantization of compact symplectic manifolds that can locally be modelled by a toric manifold, using a real polarization modelled on fibres of the moment map. We compute the results directly, and obtain a theorem similar to Sniatycki's, which gives the quantization in terms of counting Bohr-Sommerfeld leaves. However, the count does not include the Bohr-Sommerfeld leaves which are singular. Thus the quantization obtained is different from the quantization obtained using a Kaehler polarization.
