Seiberg Duality - Generalizations

Generalizations

Seiberg duality has been generalized in many directions. One generalization applies to quiver gauge theories, in which the flavor symmetries are also gauged. The simplest of these is a super QCD with the flavor group gauged and an additional term in the superpotential. It leads to a series of Seiberg dualities known as a duality cascade. It was introduced by Matthew Strassler and Igor Klebanov in Supergravity and a Confining Gauge Theory: Duality Cascades and SB-Resolution of Naked Singularities.

It is not known whether Seiberg duality exists in 3-dimensional nonabelian gauge theories with only 4 supercharges, although a conjecture has appeared in Fractional M2-branes in some special cases with Chern-Simons terms.
