六维扭子与共形场论

On Twistors and Conformal Field Theories from Six Dimensions

Christian Saemann, Martin Wolf

摘要:

本文从两层时空的观点讨论了六维时空中的手征零静止质量场方程。具体地说,我们提出了一个详细的上同调分析,开发的Penrose和Penrose-Ward变换,并分析相应的轮廓积分公式。给出扭量空间作用原理。然后,我们减少六维时空的扭量空间的维度,以获得各种理论在较低维度的扭量配方。除了著名的扭量空间,我们还发现了一个新的扭量空间之间的这些减少,这原来是适合的twistorial描述的自对偶字符串。对于这些减少扭量空间,我们解释了彭罗斯和彭罗斯-沃德变换以及轮廓积分公式。

英文摘要:

We discuss chiral zero-rest-mass field equations on six-dimensional space-time from a twistorial point of view. Specifically, we present a detailed cohomological analysis, develop both Penrose and Penrose-Ward transforms, and analyse the corresponding contour integral formulae. We also give twistor space action principles. We then dimensionally reduce the twistor space of six-dimensional space-time to obtain twistor formulations of various theories in lower dimensions. Besides well-known twistor spaces, we also find a novel twistor space amongst these reductions, which turns out to be suitable for a twistorial description of self-dual strings. For these reduced twistor spaces, we explain the Penrose and Penrose-Ward transforms as well as contour integral formulae.
