Notes on Equivalences and Higgs Branches in N=2 Supersymmetric   Yang-Mills Theory
  In this paper we investigate how various equivalences between effective field theories of $N=2$ SUSY Yang-Mills theory with matter can be understood through Higgs breaking, i.e. by giving expectation values to squarks. We give explicit expressions for the flat directions for a wide class of examples.
