Description:
We establish some oscillation criteria for the following certain even order neutral delay differential equations with mixed nonlinearities:rtzn-1tα-1zn-1t'+q0(t)(xτ0tα-1x(τ0(t))+q1t(x(τ1(t))β-1x(τ1(t))+q2t(x(τ2(t))γ-1x(τ2(t))=0, t≥t0,wherez(t)=x(t)+p(t)x(σ(t)),nis even integer, andγ〉α〉β〉0.Our results generalize and improve some known results for oscillation of certain even order neutral delay differential equations with mixed nonlinearities.
