SPECIAL GEOMETRY AND TWISTED MODULI IN ORBIFOLD THEORIES WITH CONTINUOUS WILSON LINES

Abstract

Target space duality symmetries, which acts on Kähler and continuous Wilson line moduli, of a ZN (N≠2) two-dimensional subspace of the moduli space of orbifold compactification are modified to include twisted moduli. These spaces described by the cosets [Formula: see text] are special Kähler, a fact which is exploited in deriving the extension of tree level duality transformation to include higher orders of the twisted moduli. Also, restrictions on these higher order terms are derived.
