  • Abstract
    We will prove that, in some cases, if we know only three coefficients of a polynomial with positive coefficients and without any restriction on the magnitude of its degree, we can conclude that the polynomial is unstable. Namely, if P(x)=∑i=02naix2n−i is a polynomial with positive coefficients and for some qset membership, variant{1,…,n−1} it is satisfied that image , then P(x) is unstable.
