Oscillation results for second-order neutral differential equations of mixed type

“…In [3]- [5], the authors gave some sufficient conditions for oscillation of all solutions of second-order half-linear differential equation…”

Oscillation and Asymptotic Behavior for nth-order Nonlinear Neutral Delay Dynamic Equations on Time Scales

“…where τ 0 ≥ 0, β > 0 are constants, Xu and Meng [19] gave some oscillation criteria for (1.3), which improved the main results of [20][21][22][23]. Agarwal et al [14] also considered neutral equation (1.3) with a(t) = 1 and n even, and extended the results presented in [24].…”

“…Agarwal et al [14] also considered neutral equation (1.3) with a(t) = 1 and n even, and extended the results presented in [24]. Very recently, Meng and Xu [25] offered some sufficient conditions for the oscillation of (1.3) under the condition (1.5) and the assumptions that a (t) > 0 and δ (t) > 0, and improved and extended the main results in [14,[18][19][20][21][22][23].…”
