Abstract
Microscopic tests of the exact results are performed in N = 2 SU(2) su persymmetric QCD. We construct the multiinstanton solution in N = 2 su persymmetric QCD and calculate the two-instanton contribution F-2 to t he prepotential F explicitly. For N-f = 1,2, instanton calculus agrees with the prediction of the exact results, however, for N-f = 3, we fi nd a discrepancy between them.
