Singular Phases of Seiberg-Witten Integrable Systems : Weak and Strong Coupling

  title={Singular Phases of Seiberg-Witten Integrable Systems : Weak and Strong Coupling},
  author={H. W. Braden and Andrey I. Marshakov},
We consider the singular phases of the smooth finite-gap integrable systems arising in the context of Seiberg-Witten theory. These degenerate limits correspond to the weak and strong coupling regimes of SUSY gauge theories. The spectral curves in such limits acquire simpler forms: in most cases they become rational, and the corresponding expressions for coupling constants and superpotentials can be computed explicitly. We verify that in accordance with the computations from quantum field theory… CONTINUE READING
