摘要：
The article discusses the stability of linear differential equations with time-varying coefficients.It is shown that, in contrast to equations with time-invariant coefficients, the condition for the characteristicpolynomial to be Hurwitz for a linear differential equation with time-varying coefficients is neither necessarynor sufficient for the asymptotic stability of the differential equation. It is proved that the analog of Kharitonov'stheorem on robust stability does not hold if the coefficients of the differential equation are time-varying.
