Polynomials in one variable and ranks of certain tangent maps

Published 2010-10-02, updated 2011-05-25Version 4

We study a map that sends a monic degree n complex polynomial f(x) without multiple roots to the collection of n values of its derivative at the roots of f(x). We give an answer to a question posed by Ju.S. Ilyashenko.
