Seiberg's duality and N=2 Supersymmetric QCD

Starting from the Seiberg-Witten solution of N=2 SQCD with the U(N) gauge group and N_f quark flavors we construct the so-called \mu-dual N=1 theory in the r-vacua in the regime of large values \mu of the mass of the adjoint matter, where r is the number of condensed quarks. The strong-weak coupling duality is shown to exist in the so-called zero vacua which can be found at $r< N_f-N$. We show that the \mu-dual theory matches the Seiberg's dual in the zero vacua.
