Abstract

Consider the first-order linear differential equation with several retarded arguments x′ (t)+?mi =1 pi (t)x (ti (t)) = 0, t ≥ t0, where the functions pi, ti ∈ C 􀀀 [t0,¥) , R+ ) , for every i = 1,2, . . . ,m, ti (t) ≤ t for t ≥ t0 and limt→¥ti (t) = ¥. A survey of the most interesting oscillation conditions are presented. An example illustrating the results is given.
