Regularity of roots of polynomials

Adam Parusinski, Armin Rainer

We show that smooth curves of monic complex polynomials $P_{a} (Z) = Z^{n} + \sum_{j = 1}^{n} a_{j} Z^{n - j}$ , $a_{j} : I \to C$ with $I \subset R$ a compact interval, have absolute…

A new proof of Bronshtein's theorem

Adam Parusinski, Armin Rainer

We give a new self-contained proof of Bronshtein's theorem, that any continuous root of a $C^{n - 1, 1}$ -family of monic hyperbolic polynomials of degree $n$ is locally Lipschitz, and…
