Abstract
For d=4, N=1 supersymmetric string theories we compute the quantum corrections to the superpotential to two-loop order. The vanishing of the amplitudes relies crucially on generalized Riemann identities. Beyond genus one, these map to non-trivial zeroes of theta functions implied by the Riemann vanishing theorem.
