Abstract:

In this paper the forced neutral differential equation with positive and negative coefficients

$\frac{d}{{dt}}\left {x(t) - R(t)x(t - r)} \right] + P(t)x(t - \tau ) - Q(t)x(t - \sigma ) = f(t),t_0 ,$

is considered, where f ε L ¹(t ₀, ∞) ∩ C (t ₀, ∞),R), P,Q,R ε C (t ₀, ∞), R ⁺) and r,τ,σ∈(0, ∞). The sufficient conditions to oscillate for all solutions of this equation are studied.
