Saddle point equations in Seiberg-Witten theory
Sergey Shadchin
N=2 supersymmetric Yang-Mills theories for all classical gauge groups, that is, for SU(N), SO(N), and Sp(N) is considered. The equations which define the Seiberg-Witten curve are p…

ABCD of instantons
Nikita Nekrasov, Sergey Shadchin
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…
