Vortex solutions of the Popov equations

Abstract

Popov recently discovered a modified version of the Bogomolny equations for abelian Higgs vortices, and showed they were integrable on a sphere of curvature 1/2. Here we construct a large family of explicit solutions, where the vortex number is an even integer. There are also a few solutions without vortices. The solutions are constructed from rational functions on the sphere.
