复曲面Sasaki-Einstein七流形和AdS_4/CFT_3的注记

Notes on toric Sasaki-Einstein seven-manifolds and AdS_4/CFT_3

Dario Martelli, James Sparks

摘要:

本文研究了Sasaki-Einstein七维流形的两个无穷族Y^{p,k}的几何和拓扑,它们被认为是N=2超共形场论族的AdS_4/CFT_3对偶.这些流形分别用两个正整数p和k表示,它们是CP ^2和CP ^1 x CP ^1上的Lens空间丛S ^3/Z_p。相应的Calabi-Yau锥是复曲面的。我们给出了它们的复曲面图和关于p和k的规范线性西格玛模型荷,并发现Y^{p,k}流形内插在齐次空间S^7,M^{3,2}和Q^{1,1,1}的某些轨道折叠之间.

英文摘要:

We study the geometry and topology of two infinite families Y^{p,k} of Sasaki-Einstein seven-manifolds, that are expected to be AdS_4/CFT_3 dual to families of N=2 superconformal field theories in three dimensions. These manifolds, labelled by two positive integers p and k, are Lens space bundles S^3/Z_p over CP^2 and CP^1 x CP^1, respectively. The corresponding Calabi-Yau cones are toric. We present their toric diagrams and gauged linear sigma model charges in terms of p and k, and find that the Y^{p,k} manifolds interpolate between certain orbifolds of the homogeneous spaces S^7, M^{3,2} and Q^{1,1,1}.
