The goal of this paper was to study the oscillations of a class of fourth-order nonlinear delay
differential equations with a middle term. Novel oscillation theorems built on a proper Riccati …

This study aims to investigate the asymptotic behavior of a class of third-order delay
differential equations. Here, we consider an equation with a middle term and several delays …

In this study, some new results are obtained on asymptotic behavior and stability analysis of
the mixed type differential equation x′ t=∫− 1 0 xt− r 1 θ dv θ+∫− 1 0 xt+ r 2 θ dη θ, where …

Mixed differential equations with advance and delay occur in many problems in economy,
biology, physics and engineering. The concept of delay is related to the memory of systems …

The goal of this paper is to study the oscillatory and stability of the mixed type difference
equation with variable coefficients\[\Delta x (n)=\sum_ {i= 1}^{\ell} p_ {i}(n) x (\tau …

The goal of this paper is to study the oscillatory and stability of the mixed type difference
equation with variable coefficients Δ x (n)=∑ i= 1 lpi (n) x (τ i (n))+∑ j= 1 mqj (n) x (σ i (n)) …
