摘要

BASED on the Nussbaum's results, we studied in ref. the conditions for the existence of oscillatory periodic solutions to the differential-delay equations (DDEs). in which [ a ] stands for the maximal integer which is not greater than a. Suppose that (H_0) f: ∈ C~0(R, R) is an odd function, xf (x) >=0, both lim f(x)/x = α and lim f(x)/x = β exist (α = + ∞ or β= + ∞ is included and if β= + ∞, then f(x) is increasing).
