Towards a Classification of Charge-3 Monopoles with Symmetry

Abstract

We classify all possible charge-3 monopole spectral curves with non-trivial automorphism group and within these identify those with elliptic quotients. By focussing on elliptic quotients the transcendental constraints for a monopole spectral curve become ones regarding periods of elliptic functions. We construct the Nahm data and new monopole spectral curves with $D_6$ and $V_4$ symmetry discovering a previously-unknown (to us) integrable complexification of Euler's equations. Extensions of our approach to higher charge and hyperbolic monopoles are discussed
