ABSTRACT
This paper considers the problem of identifying regions
in the complex-plane, such that the phase of polynomials
having roots in those regions, is bounded by that of a few
extreme polynomials. Applications of the results are also
described.
1 Introduction
This short paper considers the problem of identifying re-
gions in the complex-plane, such that the phase of poly-
nomials having roots in those regions, is bounded by that
of a few extreme polynomials. More specifically, given a
family of polynomials P(z-1
