Abstract: We investigate the algebraogeometric structure which is inherent in 2dimensional conformally invariant quantum field theories with N=2 supersymmetry, and its relation to the CalabiYau manifolds which appear in the socalled "large radius limit". Based on a careful comparison of the Kähler cone of CalabiYau manifolds and the moduli space of marginal chiral fields in string theory, we give a precise definition of this limit. The possibility of "flopping" between manifolds of different topology implies that the large radius limit of a given conformal model is ambiguous, and that the instantons in string theory could smooth out some of the singularities present in the classical moduli space. Since the mirror symmetry implies that the duality group of the stringy moduli space in a topological basis is at least Sp(b3, Z)×Sp(b13, Z), we are able to identify the generalization of the "R → 1/R" symmetry in c=1 models to any (2,2) model. © 1991.
