  • Abstract
    Let a family of polynomials be P(s)=t 0sn+t1s n±1 + . . . + tn where 0<aj⩽tj⩽b j. V.L. Kharitonov (1978) derived a necessary and sufficient condition for the above equation to have only zeros in the open left-half plane. The present authors derive some similar results for the equation to be strictly aperiodic (distinct real roots)
