On the Uniqueness of Vortex Equations and Its Geometric Applications

Li, Qiongling

Abstract

We study the uniqueness of a vortex equation involving an entire function on the complex plane. As geometric applications, we show that there is a unique harmonic map u : C → H^2 satisfying ∂u ≠ 0 with prescribed polynomial Hopf differential; there is a unique affine spherical immersion u : C → R^3 with prescribed polynomial Pick differential. We also show that the uniqueness fails for non-polynomial entire functions with finitely many zeros.
