Using Real-Variable Techniques to Study Zeros of Complex-Valued Harmonic Functions

Published 17 Jun 2025 in math.CV | (2506.14966v1)

Abstract: We investigate the zeros of two one-parameter families of harmonic functions and describe how the number of zeros depends on the parameter. Our functions have the property that all zeros lie on certain rays in the complex plane and thus we are able to use real-variable techniques to count the zeros on each ray.
