Seiberg-Witten and "Polyakov-like" magnetic bion confinements are continuously connected

Understand

We study four-dimensional N=2 supersymmetric pure-gauge (Seiberg-Witten) theory and its N=1 mass perturbation by using compactification S**1 x R**3.

• It is well known that on R**4 (or at large S**1) the perturbed theory realizes confinement through monopole or dyon condensation.
• At small S**1, we demonstrate that confinement is induced by a generalization of Polyakov's three-dimensional instanton mechanism to a locally four-dimensional theory - the magnetic bion mechanism - which also applies to a large class of nonsupersymmetric theories.
• Using a large- vs.
