The stability region for Schur stable trinomials with general complex coefficients

Gerardo Barrera, Waldemar Barrera, Juan Pablo Navarrete

In this paper, we characterize the stability region for trinomials of the form $f(\zeta ):=a{\zeta }^n+b{\zeta }^m+c$, $\zeta \in \mathbb{C}$, where $a$, $b$ and $c$ are non-zero complex numbers and $n…
