Conformal Field Theory and the Reid Conjecture

Abstract

We construct special pairs of quantum sigma models on Kahler Calabi-Yau and non-Kahler Fu-Yau manifolds which flow to the same conformal field theories in their "small-radius" phases. This smooth description of a novel type of topology change constitutes strong evidence for Reid's conjecture on the connectedness of moduli spaces of Kahler and non-Kahler manifolds with trivial canonical class.
