  • Abstract
    It is shown that, for the equation frac{d^{2}u}{dt^{2}} + \\mu frac{du}{dt} + g (t,u,frac{du}{dt}) {u + \\lambda frac{du}{dt}} = 0 , the maximum value of β for which asymptotic stability can be guaranteed with a < g(t, u, du/dt) < \\beta (a \\geq 0) is the same whether derived by the circle criterion or by means of a quadratic Lyapunov function with constant coefficients, and this maximum value is explicitly evaluated.
