Abstract

We explicitly find the spectrum of the operators M^rs and \widetildeM^rs, which specify the star-product in the matter and ghost sectors correspondingly. Further we derive the diagonal representation for the 3-string vertices. Using this representation we identify the appearing Moyal structures in the matter sector. In addition to the continuous non-commutativity parameter θ(κ) found in hep-th/0202087 we find the discrete non-commutativity parametrized by θ_ξ.
