Abstract:
We obtain the exact beta function for N=2N=2 SUSY SU(2)SU(2) Yang-Mills theory and prove the nonperturbative Renormalization Group Equation ΛF(a,Λ)=ΛΛ0Λ0F(a0,Λ0)e 2τ0 τdxβ 1(x). \partial_\Lambda{\cal F}(a,\Lambda)= {\Lambda\over \Lambda_0}\partial_{\Lambda_0}{\cal F}(a_0,\Lambda_0) e~{-2\int_{\tau_0}~\tau {dx \beta~{-1}(x)}}.
