Abstract: I will talk about a set of tools for proving regularity of plethystic logarithms. For instance, we deduce that the generating series of Frobenius characters of a power of the Procesi bundle on the Hilbert scheme, which is of great importance, has only simple poles in q and t after taking the plethystic logarithm. Considering the asymptotic q,t->1, one can also deduce results about regularity of series appearing in instanton counting.
