 Seiberg–Witten theory

In theoretical physics, Seiberg–Witten theory is a theory that determines an exact low-energy effective action (for massless degrees of freedom) of a formula_1 supersymmetric gauge theory—namely the metric of the moduli space of vacua.In general, effective Lagrangians of supersymmetric gauge theories are largely determined by their holomorphic properties and their behavior near the singularities.
