Abstract:
Using instanton calculus we check, in the weak coupling region, the nonperturbative relation <\Tr\phi~2>=i\pi\left(\cf-{a\over 2} {\partial\cf\over\partial a}\right) obtained for a N=2 globally supersymmetric gauge theory. Our computations are performed for instantons of winding number k, up to k=2 and turn out to agree with previous nonperturbative results.- 11.15.Tk
