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 Calabi-Yau hypersurfaces in weighted projective spaces and Landau-Ginzberg 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 world-sheet supersymmetry. The construction also predicts the possibility of certain physical processes involving a change in the topology of space-time.- gauge field theory: Yang-Mills
