Diagonal Representation of Open String Star and Moyal Product
arXiv:hep-th/0204164
Abstract
We explicitly find the spectrum of the operators and , 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 found in hep-th/0202087 we find the discrete non-commutativity parametrized by .
