Mirror Symmetry and Discriminants Aspinwall, Paul


We analyze singularities in the parameter space of the gauged linear sigma model and show how they coincide with the GKZ A-determinant in the noncompact case. We show that this requires logarithmic coordinates to work correctly. The same analysis gives a natural picture for generic monodromy in the derived category around components of the discriminant in terms of specific spherical functors.
