复曲面几何和局部卡-丘变体:复曲面几何导论(物理学家)

Toric geometry and local Calabi-Yau varieties: An introduction to toric geometry (for physicists)

Cyril Closset

摘要:

这些课堂讲稿是对复曲面几何的介绍。特别是把重点放在描述的环面本地卡-丘品种,如需要在应用程序中的AdS/CFT对应弦论。在这些讲座中采取的观点大多是代数几何,但没有事先知识的代数几何是假定的。在介绍了必要的数学定义之后,我们讨论了作为全纯代数的复曲面簇的构造。讨论复曲面Calabi-Yau奇点的分解和形变。我们还解释了规范线性西格玛模型(GLSM)的Kahler商的建设。

英文摘要:

These lecture notes are an introduction to toric geometry. Particular focus is put on the description of toric local Calabi-Yau varieties, such as needed in applications to the AdS/CFT correspondence in string theory. The point of view taken in these lectures is mostly algebro-geometric but no prior knowledge of algebraic geometry is assumed. After introducing the necessary mathematical definitions, we discuss the construction of toric varieties as holomorphic quotients. We discuss the resolution and deformation of toric Calabi-Yau singularities. We also explain the gauged linear sigma-model (GLSM) Kahler quotient construction.
