允许光滑扩张的分离变量星积
Star products with separation of variables admitting a smooth extension
摘要:
给定一个复流形$M$,其具有一个开稠密子集$Ω$,该子集被赋予一个伪Kaehler形式$ω$,该形式不能平滑地扩展到一个更大的开子集,我们考虑各种例子,其中相应的Kaehler-Poisson结构和$(Ω, ω)$上具有分离变量的星积允许对$M$的平滑扩展。我们提出了一个简单的标准存在的一个光滑的扩展的明星产品,并将其应用到这些例子。
英文摘要:
Given a complex manifold $M$ with an open dense subset $Ω$ endowed with a pseudo-Kaehler form $ω$ which cannot be smoothly extended to a larger open subset, we consider various examples where the corresponding Kaehler-Poisson structure and a star product with separation of variables on $(Ω, ω)$ admit smooth extensions to $M$. We suggest a simple criterion of the existence of a smooth extension of a star product and apply it to these examples.
