AB - This note is presenting the generating functions which count the BPSoperators in the chiral ring of a N=2 quiver gauge theory that lives on N D3branes probing an ALE singularity. The difficulty in this computation arisesfrom the fact that this quiver gauge theory has a moduli space of vacua thatsplits into many branches -- the Higgs, the Coulomb and mixed branches. As aresult there can be operators which explore those different branches and thecounting gets complicated by having to deal with such operators while avoidingover or under counting. The solution to this problem turns out to be veryelegant and is presented in this note. Some surprises with "surgery" ofgenerating functions arises.
