Zero location for analytic and harmonic trinomials
We derive zero inclusion sectors for both analytic and harmonic trinomials, as well as sector dependent lower bounds on the magnitudes of their zeros. In addition, we determine the minimum and maximum number of zeros of a harmonic trinomial from basic arguments. Examples illustrate the theory.
