从几何到共形域论的K3

K3 en route From Geometry to Conformal Field Theory

Katrin Wendland

摘要:

为了为从几何学到共形域论(CFT)的旅程铺平道路,这些笔记提供了从卡-丘几何学中构造一些基本CFT的背景。主题包括复杂和凯勒几何的卡-丘流形和他们的分类在低维。此外,我讨论CFT结构的最简单的已知的例子,是基于卡-丘几何,即为超共形的环形域论和他们的Z2-orbifolds。在途中从几何CFT,我提供了一个讨论的K3表面作为最简单的一类卡-丘流形,非线性西格玛模型的建设承担的奥秘非常一天。椭圆亏格在CFT和几何被召回作为一个指导性的证据,有利于几何和共形域论之间的深刻联系。

英文摘要:

To pave the way for the journey from geometry to conformal field theory (CFT), these notes present the background for some basic CFT constructions from Calabi-Yau geometry. Topics include the complex and Kaehler geometry of Calabi-Yau manifolds and their classification in low dimensions. I furthermore discuss CFT constructions for the simplest known examples that are based in Calabi-Yau geometry, namely for the toroidal superconformal field theories and their Z2-orbifolds. En route from geometry to CFT, I offer a discussion of K3 surfaces as the simplest class of Calabi-Yau manifolds where non-linear sigma model constructions bear mysteries to the very day. The elliptic genus in CFT and in geometry is recalled as an instructional piece of evidence in favor of a deep connection between geometry and conformal field theory.
