通过考察Harvey，Kutasov，Martinec和Moore最近的提议，我们考虑了局域闭弦快子的凝聚。我们首先观察到当模型具有超对称时，由HKMM定义的GCL不能反映时空的超对称性。特别是对于C2/ZN模型，由它们定义的GCL在ORBORBLOW空间的超对称点上达到高度峰值，这不是RG流的C-函数的令人满意的性质。在第二类情形下，我们给出了修正的GCL的定义，使得它在orbillold模空间中的超对称点上有一个谷。新的定义预测，亚当斯、波尔钦斯基和西尔弗斯坦建议的、被HKMM认为是禁止的过程实际上是允许的。
We consider condensation of localized closed string tachyons by examining the recent proposal of Harvey, Kutasov, Martinec, and Moore. We first observe that the gcl defined by HKMM does not reflect the space-time supersymmetry when the model has the SUSY. Especially for C 2 /ZN models, gcl defined by them is highly peaked along the supersymmetric points in the space of orbifolds, which is unsatisfactory property of the c-function of the RG-flow. We give the modified definition of the gcl in type II cases such that it has a valley along the supersymmetric points in the orbifold moduli space. New definition predicts that the processes suggested by Adams, Polchinski and Silverstein and was argued to be forbidden by HKMM are in fact allowed.
