Seiberg duality (named after (Seiberg)) is a version of electric-magnetic duality in supersymmetric gauge theory.

For supersymmetric QCD it identifies in the infrared (long distance limit, and only there) the quarks and gluons in a theory with N fN_f quark flavors and SU(N c)SU(N_c) gauge group for

N f>N c+1 N_f \gt N_c +1

with solitons in a theory of N fN_f quark flavors and gauge group SU(N˜ c)SU(\tilde N_c), where

N˜ c=N fN c. \tilde N_c = N_f - N_c \,.


Realization in string theory

Seiberg duality follows from phenomena in string theory, where gauge theories arise as the worldvolume theories of D-branes (geometric engineering of quantum field theory). Seiberg duality is obtained for gauge theories of D-branes that stretch between two NS5-branes. The duality operation corresponds to exchanging the two NS5-branes.

Formalization by derived quiver categories

Seiberg duality is formalized by equivalences of derived categories of quiver representations.


Toric duality

Toric Duality is Seiberg duality for N=1N=1 theories with toric moduli spaces.
