## Properties of the third order trinomial differential equations with delay argument.(English)Zbl 1173.34348

Summary: We study properties of the third order trinomial delay differential equation $y^{\prime \prime \prime }(t)+p(t)y{^{\prime}}(t)+g(t)y(\tau (t))=0$
by transforming this equation to a binomial second/third order differential equation. Employing suitable comparison theorems we establish new results on the asymptotic behavior of solutions.
