Abstract
We derive an explicit expression for a current-current correlation fun ction on a Riemann surface represented as 3 sheets ramified covering o ver CP(1). The method used in the paper can be easily applied to more general algebraic curves. Knowledge of G(z,w) enables calculation of t he expectation value of the energy momentum tensor for scalar field.
