Phases of N = 2 theories in two dimensions
Abstract
By looking at phase transitions which occur as parameters are varied in supersymmetric gauge theories, a natural relation is found between sigma models based on CalabiYau hypersurfaces in weighted projective spaces and LandauGinzburg models. The construction permits one to recover the known correspondence between these types of models and to greatly extend it to include new classes of manifolds and also to include models with (0,2) worldsheet supersymmetry. The construction also predicts the possibility of certain physical processes involving a change in the topology of spacetime.
