CORRELATION FUNCTIONS FOR M<sup>N</sup>/S<sub>N</sub> ORBIFOLDS

CORRELATION FUNCTIONS FOR M<sup>N</sup>/S<sub>N</sub> ORBIFOLDS

We consider a bosonic CFT on a noncommutative orbifold M n /S n . To calculate three and four point functions of the twist operators on such an orbifold we perform a conformal map to the covering space and evaluate an appropriate Liouville action. We give an expression for the …
