The asymptotic stability of the solutions of the differential equation x "
+ h(t)x ' + x = 0 is investigated under the restrictions that h(t) = 2h(n)
> 0 on [t(n),t(n) + tau (n)], and h(t) = 0 elsewhere, lim(n --> infinity) t
(n) = infinity and t(n)+1 - t(n) is not necessarily a multiple of pi, n eps
