More on Seiberg-Witten Theory and Monstrous Moonshine

We continue the study of a relationship between the instanton expansion of the Seiberg-Witten (SW) prepotential of $D=4$, $\mathcal{N}=2$ $SU(2)$ SUSY gauge theory and the monstrous moonshine. Extending the previous results, we show for the cases of $N_f=2$ and $3$ that $q=e^{2\pi i\tau }$, where $\tau$ is the complex gauge coupling, again has an expansion whose coefficients are all integer-coefficient polynomials of the moonshine coefficients of the modular $j$-function in terms of an appropriate expansion variable. We also demonstrate that the new method of calculating the SW prepotential developed here is useful by performing some explicit computations.
