Stability of roots of polynomials under linear combinations of derivatives

Branko Ćurgus, Vania Mascioni

Let $T = α_{0} I + α_{1} D + ... + α_{n} D^{n}$ , where $D$ is the differentiation operator and $α_{0} \neq = 0$ , and let $f$ be a square-free polynomial with large minimum root separation. We prov…

Perturbations of roots under linear transformations of polynomials

Branko Ćurgus, Vania Mascioni

Let $\cP_n$ be the complex vector space of all polynomials of degree at most $n$ . We give several characterizations of the linear operators $T\in\cL(\cP_n)$ for which there exists…
