本文研究了低能D3-膜上场论的边缘形变。这些理论包括N = 4超对称杨-米尔斯理论和通过轨道折叠过程从它获得的理论。我们仅限于使某些超对称性不破缺的轨道折叠和形变。我们发现了一些新的N = 1超共形场论族，并利用微扰方法和一般的方法对精确边缘形变空间的维数进行了分析。我们发现一些情况下，空间的微扰正好边际变形小于预测的一般分析（至少到三个循环顺序），和其他情况下，微扰的结果（在低阶）有一个非通用的形式。
In this paper we study exactly marginal deformations of field theories living on D3-branes at low energies. These theories include N = 4 supersymmetric Yang-Mills theory and theories obtained from it via the orbifolding procedure. We restrict ourselves only to orbifolds and deformations which leave some supersymmetry unbroken. A number of new families of N = 1 superconformal field theories are found. We analyze the deformations perturbatively, and also by using general arguments for the dimension of the space of exactly marginal deformations. We find some cases where the space of perturbative exactly marginal deformations is smaller than the prediction of the general analysis (at least up to three-loop order), and other cases where the perturbative result (at low orders) has a non-generic form.
