扭Virasoro算子与数论

On Twisted Virasoro Operators and Number Theory

An Huang

摘要:

探讨了发散级数的几个公理及其与共形场论的关系。因此,当$χ$是Dirichlet特征标时,我们得到了计算$L(0,χ)$和$L(-1,χ)$的另一种方法.我们希望这个讨论也能引起做重整化理论的物理学家的兴趣,原因在引言部分已经提到了。我们引入一个扭曲的振荡器表示的维拉索罗代数的一组狄利克雷字符,并使用此给出一个“物理解释”,为什么某些发散系列的值应给予特殊的L值。此外,我们用它来表明,一些分数的权力,这是至关重要的一些无限的产品,以具有独特的模变换性能明确表示的某些线性组合的$L(-1, χ)$的适当选择的$χ$的,并可以理解为一种“真空卡西米尔能量”在我们的设置。我们还注意到场论和我们的扭曲算子之间的关系。最后,我们尝试用数域上的一种共形场论来重新解释Tate的论文。

英文摘要:

We explore some axioms of divergent series and their relations with conformal field theory. As a consequence we obtain another way of calculating $L(0,χ)$ and $L(-1,χ)$ for $χ$ being a Dirichlet character. We hope this discussion is also of interest to physicists doing renormalization theory for a reason indicated in the Introduction section. We introduce a twist of the oscillator representation of the Virasoro algebra by a group of Dirichlet characters and use this to give a 'physical interpretation' of why the values of certain divergent series should be given by special L values. Furthermore, we use this to show that some fractional powers which are crucial for some infinite products to have peculiar modular transformation properties are expressed explicitly by certain linear combinations of $L(-1, χ)$'s for appropriately chosen $χ$'s, and can be understood physically as a kind of 'vacuum Casimir engergy' in our settings. We also note a relation between field theory and our twisted operators. Lastly we give an attempt to reinterpret Tate's thesis by a sort of conformal field theory on a number field.
