On oscilatory fourth order nonlinear neutral differential equations – IV

Year, pages: 2019, 1099 - 1116

In this paper, oscillation of all solutions of fourth order functional differential equations of neutral type of the form \begin{equation*} (r(t)(y(t)+p(t)y(t-τ))'')''+q(t)G(y(t-σ))=0 \end{equation*} are studied under the assumption \begin{equation*} \int^∞₀((t) / (r(t)))\dt<∞ \end{equation*} for various ranges of $p(t)$
