Moduli spaces of framed perverse instantons on P^3

Abstract

We study moduli spaces of framed perverse instantons on P^3. As an open subset it contains the (set-theoretical) moduli space of framed instantons studied by I. Frenkel and M. Jardim. We also construct a few counterexamples to earlier conjectures and results concerning these moduli spaces.
