Abstract
We exhibit a close relation between vortex configurations on the 2sphere and magnetic zeromodes of the Dirac operator on (Formula presented.) which obey an additional nonlinear equation. We show that both are best understood in terms of the geometry induced on the 3sphere via pullback of the round geometry with bundle maps of the Hopf fibration. We use this viewpoint to deduce a manifestly smooth formula for squareintegrable magnetic zeromodes in terms of two homogeneous polynomials in two complex variables.
