Abstract :
Given a polynomial which is Hurwitz or which has zeros only within or on the unit circle, it is of interest to know how much the coefficients tjcan be perturbed while preserving the stability properties. In this note, a method is presented for obtaining the largest hypersphere centered at containing only polynomials which are stable.
