 Title: On Root Arrangements of Polynomial-Like Functions and their Derivatives Authors: Kostov, Vladimir Keywords: Hyperbolic PolynomialRoot ArrangementConfiguration Vector Issue Date: 2005 Publisher: Institute of Mathematics and Informatics Bulgarian Academy of Sciences Citation: Serdica Mathematical Journal, Vol. 31, No 3, (2005), 201p-216p Abstract: We show that for n = 4 they are realizable either by hyperbolic polynomials of degree 4 or by non-hyperbolic polynomials of degree 6 whose fourth derivatives never vanish (these are a particular case of the so-called hyperbolic polynomial-like functions of degree 4).
