摘要：

In our previous papers, we prove the no-ghost theorem without light-cone directions ([1, 2]). We point out that our results are valid for more general backgrounds. In particular, we prove the no-ghost theorem for AdS(3) in the context of the BRST quantization (with the standard restriction on the spin). We compare our BRST proof with the OCQ proof and establish the BRST-OCQ equivalence for AdS(3). The key in both approaches ties in the certain structure of the matter Hilbert space as a product of two Verma modules. We also present the no-ghost theorem in the most general form.
