Doru Stefanescu: On some absolute positiveness bounds, p.269-276

Abstract:

We prove that some bounds for positive roots of univariate polynomials with real coefficients are absolute positiveness bounds. It is also proved that there exist positiveness bounds which are not absolute.

Key Words: Bound for absolute positiveness, Polynomial zeros.
