本文计算了与q = eiπ/k量子群相关联的k个变形sigma模型的世界片上可能的边缘耦合的单圈β函数。这包括玻色子主手征模型和对称空间σ模型，也包括描述AdS 5 × S5变形弦的k变形半对称空间σ模型。世界片sigma模型是PSU（2，2）超群规范WZW模型的流-流变形|4）k级。在弦理论中，由于PSU（2，2）的Killing形式的消失，β函数被证明为消失|这是另一个证明k变形理论定义相容弦理论的证据。
A bstractWe calculate the one loop beta function for the would-be marginal coupling on the world sheet of the k deformed sigma models associated to a quantum group with q = eiπ/k. This includes the bosonic principal chiral models and symmetric space sigma models but also the k deformed semi-symmetric space sigma model describing strings in a deformation of AdS5 × S5. The world sheet sigma model is a current-current deformation of the gauged WZW model for the supergroup PSU(2, 2|4) with level k. In the string theory context the beta function is shown to vanish because of the vanishing of the Killing form of PSU(2, 2|4) which is another piece of evidence that the k deformed theories define consistent string theories.
