| Abstract: | I will show how the Nekrasov partition function, expanded in a certain two parameters way, can be described by a world sheet theory involving Riemann surfaces with genus counting associated to both the parameters. I will present the most general ansatz compatible with the holomorphic anomaly equation respected by those amplitudes and derive all the possible conditions that have to be satisfied. Finally I will try to give some physical insight for this model and present my conclusions. |
