Seiberg–Witten moduli space

In gauge theory, the Seiberg–Witten moduli space (short SW moduli space, also monopole moduli space) is the moduli space of the Seiberg–Witten equations, hence the space of its solutions up to gauge. It is used to defined the Seiberg–Witten invariants used to study four-dimensional smooth manifolds (short 4-manifolds).
