## On asymptotic behavior of delay-differential equations of third order.(English)Zbl 0935.34063

The asymptotic behavior of nonoscillatory solutions to third-order delay-differential equations $y'''(t)+a(t)y''(t)+b(t)y'(t)+c(t)y(g(t))=0$ is studied where $$a,b,c \in C([0,\infty),\mathbb{R})$$, $$a(t)\geq 0$$, $$b(t)\leq 0$$, $$c(t)> 0$$ and $$g\in C([0,\infty),\mathbb{R})$$ with $$g(t)\leq t$$ and $$g(\infty)=\infty$$.
