Perturbation on Polynomials
For univariate polynomials with complex coefficients there are many estimates about the roots of polynomials. Moreover, the result corresponding to the “continuity of the zeroes which respect to the coefficients” is generally obtained as a corollary of Rouche ?’s theorem and is rarely precise. Here we prove an explicit result for algebraically closed fields with an absolute value, in any characteristic.
