Abstract

Self-dual Yang-Mills instantons on R4R^4 correspond to algebraic ADHM data. The ADHM equations for S1S^1-symmetric instantons give a one-dimensional integrable lattice system, which may be viewed as an discretization of the Nahm equations. In this note, we see that generalized ADHM data for T2T^2-symmetric instantons gives an integrable two-dimensional lattice system, which may be viewed as a discrete version of the Hitchin equations.
