Abstract
In this paper, oscillation and asymptotic behaviour of solutions of \(y''' + a(t)y'' + b(t)y' + c(t)y = 0\) have been studied under suitable assumptions on the coefficient functions \(a,b,c \in C([\sigma ,\infty ),\mathbb{R}),{\text{ }}\sigma \in \mathbb{R}\) such that a(t ≥ 0, b(t) ≤ 0 and c(t) < 0.
