非紧G/Ad(H)模型的模不变配分函数

Modular invariant partition functions for non-compact G/Ad(H) models

Jonas Bjornsson, Jens Fjelstad

摘要:

我们提出了一类规范的非紧G/Ad(H)WZNW模型,包括最高,最低和混合极值权重模块的频谱流图像的频谱。这些被组合成块,其字符,由于目标空间的洛伦兹签名,是发散的,并被视为需要正则化的正式表达式。假设这是可能的,我们表明,这些扩展字符下的模块化变换线性变换,并可以用来写下来模块不变的配分函数。

英文摘要:

We propose a spectrum for a class of gauged non-compact G/Ad(H) WZNW models, including spectrally flowed images of highest, lowest, and mixed extremal weight modules. These are combined into blocks whose characters, due to the Lorentzian signature of the target space, are divergent and treated as formal expressions in need of regularisation. Assuming that this is possible, we show that these extended characters transform linearly under modular transformations, and can be used to write down modular invariant partition functions.
