Discrete Nahm Equations for SU(N) Hyperbolic Monopoles
Abstract
In a paper of Braam and Austin, magnetic monopoles in hyperbolic space were shown to be the same as solutions to matrix-valued difference equations called the discrete Nahm equations. Here, I discover the -interval discrete Nahm equations and show that their solutions are equivalent to hyperbolic monopoles. These discrete time evolution equations on an interval feature a jump in matrix dimensions at certain points in the evolution, which are given by the mass data of the corresponding monopole. I prove the correspondence with higher rank hyperbolic monopoles using localisation and Chern characters. I then prove that the monopole is determined up to gauge transformations by its "holographic image" of fields at the asymptotic boundary of .
