Abstract
We obtain a comparison result for the oscillation of all solutions of the equation [GRAPHICS] in terms of the oscillation of all solutions o f the equation [GRAPHICS] under appropriate hypotheses on the asymptot ic behavior of the quotients p(i)(t)/q(i)(t) and tau(i)(t)/sigma(i)(t) for i = 1, 2,..., n. An application to the oscillation of the nonauto nomous delay-logistic equation is given.
