New oscillation criteria for third order nonlinear functional differential equations [elektronikus dokumentum] / Graef John R. 2024 11 Electronic journal of qualitative theory of differential equations The authors consider the general third order functional differential equation a2(ν) a1(ν) x �α1 �α2 + q(ν)x (τ(ν)) = 0, ν ≥ ν0, and obtain sufficient conditions for the oscillation of all solutions. It is important to note that αi for i = 1, 2, and β are somewhat independent of each other. The results obtained are illustrated with examples.
