Oscillation of Neutral Differential Equations with "Integrally Small" Coefficients

Abstract:

      Sufficient conditions for the oscillation of the neutral equation d/(dt)[x(t) - R(t)x(t - r)] + P(t)x(t - τ) - Q(t)x(t - δ) = 0,where P,Q,R ∈ C([t₀,∞), R⁺), and r,τ, δ ∈ (0,∞), are obtained for the case where former results can not be applied.
