我们提出了D3膜世界体积上的超共形规范理论，探讨了最近发现的Sasaki-Einstein流形Lp，q，r的复曲面奇点。通过比较手征场的中心电荷和R-电荷与可以从复曲面几何中提取的信息，对识别进行了各种检查。分数膜也介绍了相关的对偶级联的物理讨论。
We present the superconformal gauge theory living on the world-volume of D3 branes probing the toric singularities with horizon the recently discovered Sasaki-Einstein manifolds Lp,q,r. Various checks of the identification are made by comparing the central charge and the R-charges of the chiral fields with the information that can be extracted from toric geometry. Fractional branes are also introduced and the physics of the associated duality cascade discussed.
