Zero-flee regions for a rational function with applications

Research output: Contribution to journalArticle

Abstract

In this paper, we study a rational function which plays an important role in several problems of interest (eigenvalue problems, linear control theory, ... ). Our main interest is to determine zero-free regions. We also derive upper and lower bounds for this function.
