摘要:
The sufficient conditions for asymptotic stability of solutions of second order linear differential equation y'' + p(t)y' + q(t) y = 0 with continuously differentiable coefficients p : [0; +infinity) -> R and q : [0; +infinity) -> R are established in the case where the roots of the characteristic equation lambda(2) + p(t)lambda + q(t) = 0 satisfy conditions Re lambda(i) (t) < 0 for t >= 0; integral(+infinity)(t0) Re lambda(i) (t) dt = -infinity (i = 1, 2).
