The different singularity loci are mapped in a one to one way, and the (N = 2 limit/point particle limit) is obtained in both cases by the same type of blow up. Moreover, it is shown that the S-duality group permutes the different singularity loci of the moduli of WIP^(12)_(11226). We study the transformation under S-duality of the Calabi-Yau Yukawa couplings. eng open access S-duality and the Calabi-Yau interpretation of the N=4 to N=2 flow journal article
