摘要

Consider the first-order advanced differential equation of the form x′(t)-m∑i=1 q_i(t)x(σ_i(t))=0, t≥t_0, where q_i, 1 ≤ i ≤ m are functions of non-negative real numbers, and σ_i, 1 ≤ i ≤ m are functions of positive real numbers such that σ_i(t) > t for t ≥ t_0. New oscillation criteria, involving lim sup and lim inf, are established, in the case of non-monotone advanced arguments. An example illustrating the results is also given.
