Abstract

We derive the duality symmetries relevant to moduli dependent gauge coupling constant threshold corrections, in Coxeter ZN orbifolds. We consider those orbifolds for which the point group leaves fixed a 2-dimensional sublattice Λ2, of the six dimensional torus lattice Λ6, where Λ6 cannot be decomposed as Λ2 Λ4.
