摘要
We use an improved technique to establish new sufficient criteria of product type for the oscillation of the delay differential equation x'(t) + Em l=1 bl(t)x(al(t)) = 0, t > t0, with bl, al e C([t0, oo), [0, oo)) such that al(t) < tand limt->oo al(t) = oo, l = 1,2, , m. The obtained results are applicable for the nonmonotone delay case. Their strength is supported by a detailed practical example.
