Unimodular Zeros of Selmer's Harmonic Trinomials

Let $n>k$ be positive integers and let $\varepsilon,\delta\in\{-1,1\}$. In this note, we classify the unimodular zeros of the harmonic trinomial $H_{\varepsilon,\delta}:\mathbb{C}\to \mathbb{C}$ given by \[ H_{\varepsilon,\delta}(z)=z^n+\varepsilon\overline z^{\,k}+\delta, \] where $\overline{z}$ is the complex conjuga...
