Hille–Nehari type criteria and conditionally oscillatory half-linear differential equations
Electronic Journal of Qualitative Theory of Differential Equations, 2019 We study perturbations of the generalized conditionally oscillatory half-linear equation of the Riemann–Weber type. We formulate new oscillation and nonoscillation criteria for this equation and find a perturbation such that the perturbed Riemann–Weber ...

Nonoscillations in retarded systems
Journal of Mathematical Analysis and Applications, 2005 Consider the equation \[ x(t)+ \int^0_{-1} d[\nu(\theta)]x(t- r(\theta))= 0,\tag{1} \] where \(x(t)\in \mathbb{R}^n\), \(r\in C([-1,0], \mathbb{R}_+)\), and \(\nu(\theta)\) is a real \(n\times n\) matrix valued function of bounded variation on \([-1, 0]\).

Nonoscillation of damped linear differential equations with a proportional derivative controller and its application to Whittaker-Hill-type and Mathieu-type equations [PDF]
, 2023 The proportional derivative (PD) controller of a differential operator is commonly referred to as the conformable derivative. In this paper, we derive a nonoscillation theorem for damped linear differential equations with a differential operator using ...

Journal of Mathematics, Volume 2026, Issue 1, 2026.This paper investigates the oscillatory behavior of first‐order linear differential and difference equations with several delays. The main objective is to determine whether classical liminf‐type oscillation conditions for single‐delay equations can be extended to the several‐delay setting and to develop sharp oscillation criteria for this more general ...

Discrete Dynamics in Nature and Society, Volume 2019, Issue 1, 2019., 2019 In this paper, we discuss a class of fractional differential equations of the form D-α+1y(t)·D-αy(t)-p(t)f(D-αy(t))+q(t)h∫t∞(s-t) -αy(s)ds=0.D-αy(t) is the Liouville right‐sided fractional derivative of order α ∈ (0,1). We obtain some oscillation criteria for the equation by employing a generalized Riccati transformation technique.
