Abstract |
|
|
| Consider the first-order linear differential equation with several retarded arguments x′ (t)+åmi
=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. |
