Roots and polynomials as homeomorphic spaces

Branko Ćurgus, Vania Mascioni

We provide a unified, elementary, topological approach to the classical results stating the continuity of the complex roots of a polynomial with respect to its coefficients, and th…

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 . We give several characterizations of the linear operators $T\in\cL(\cP_n)$ for which there exists…
