On the geometric interpretation of \(N=2\) superconformal theories. (English) Zbl 1052.32502

Summary: We clarify certain important issues relevant for the geometric interpretation of a large class of \(N=2\) superconformal theories. By fully exploiting the phase structure of these theories (discovered in earlier works) we are able to clearly identify their geometric content. One application is to present a simple and natural resolution to the question of what constitutes the mirror of a rigid Calabi-Yau manifold. We also discuss some other models with unusual phase diagrams that highlight some subtle features regarding the geometric content of conformal theories.
