Query: ABCD of instantons   We solve N=2 supersymmetric Yang-Mills theories for arbitrary classical gauge
group, i.e. SU(N), SO(N), Sp(N). In particular, we derive the prepotential of
the low-energy effective theory, and the corresponding Seiberg-Witten curves.
We manage to do this without resolving singularities of the compactified
instanton moduli spaces.
