Abstract
We present a self-contained study of ADHM multi-instantons in SU(N) gauge theory, especially
the novel interplay with supersymmetry and the large-N limit. We give both field- and
string-theoretic derivations of the N = 4 supersymmetric multi-instanton action and collective
coordinate integration measure. As a central application, we focus on certain n-point functions
