Real non-attractive fixed point conjecture for complex harmonic functions

Complex Variables 2025-07-25 v1

Abstract

We prove the real non-attractive fixed point conjecture for complex polynomial and rational harmonic functions. A harmonic function f=h+gf=h+\overline{g} is polynomial (rational) if both hh and gg are polynomials (rational functions) of degree at least 2. We show that every such function with a super-attracting fixed point has a h\mathfrak{h}-fixed point ζ=μ+ω\zeta=\mu+\overline{\omega} such that the real parts of its multipliers satisfy Re(zh(μ))1\text{Re}(\partial_z h(\mu)) \geq 1 and Re(zg(ω))1\text{Re}(\partial_z g(\omega)) \geq 1. For polynomial harmonic functions, this holds even without super-attracting conditions. We provide explicit examples, visualizations, and discuss problem for transcendental harmonic functions.
