A Positive Fraction Erdős-Szekeres Theorem and Its Applications

WebThe Gauss–Lucas theorem states that the convex hull of the roots of a polynomial contains the roots of the derivative of the polynomial. A sometimes useful corollary is that, if all roots of a polynomial have positive real part, then so do the roots of all derivatives of the polynomial. A related result is Bernstein's inequality.
