On the Asymptotic Behaviour of Solutions of Third Order Delay Differential Equations

Sufficient conditions in terms of coefficient functions have been obtained so that all nonoscillatory solutions along with their first and second derivatives of the third order delay differential equation $$y'''(t)+a(t)y''(t)+b(t)y'(t)+c(t)y(g(t))=0$$ tend to zero as $t\rightarrow\infty$.

Oscillation, nonoscillation, disconjugate, asymptotic behaviour, delay differential equations.
