The non-perturbative N=2 SUSY Yang-Mills theory from semiclassical absorption of supergravity by wrapped D branes -: art. no. 022

The imaginary part of the two point functions of the super conformal anomalous currents are extracted from the cross-sections of semiclassical absorption of dilaton, RR-2 form and gravitino by the wrapped D5 branes. From the central terms of the two point functions anomalous Ward identity is established which relates the exact pre-potential of the N = 2 SUSY Yang-Mills theory with the vacuum expectation value of the anomaly multiplet. Rom the Ward identity, WDVV (Witten-Dijkgraaf-Verlinde-Verlinde) equation can be derived which is solved for the exact pre-potential.
