Unimodular Zeros of Selmer's Harmonic Trinomials

Gerardo Barrera, Waldemar Barrera, Juan Pablo Navarrete

Let $n > k$ be positive integers and let $ε, δ \in {- 1, 1}$ . In this note, we classify the unimodular zeros of the harmonic trinomial $H_{\varepsilon,δ}:\mathbb{C}\to \mathbb…

On the Parameter Spaces of Harmonic Trinomial Equations

Waldemar Barrera, Lucia Campa, Juan Pablo Navarrete

We analyze the parameter space of harmonic trinomial equations of the form $z^{n + m} + b z^{m} + c$ , where $n, m \in Z^{+}$ are coprime and $b, c \in C$ . Using version…
