On Constants in Nonoscillation Criteria for Half‐Linear Differential Equations [PDF]
We study the half‐linear differential equation (r(t)Φ(x′)) ′ + c(t)Φ(x) = 0, where Φ(x) = |x|p−2x, p > 1. Using the modified Riccati technique, we derive new nonoscillation criteria for this equation. The results are closely related to the classical Hille‐Nehari criteria and allow to replace the fixed constants in known nonoscillation criteria by a ...

Sharp oscillation criteria for fourth order sub-half-linear and super-half-linear differential equations [PDF]
This paper is concerned with the oscillatory behavior of the fourth-order nonlinear differential equation $$ \bigl(p(t)|x^{\prime\prime}|^{\alpha-1}\,x^{\prime\prime}\bigr)^{\prime\prime} +q(t)|x|^{\beta-1}x=0\,,\tag{E} $$ where $\alpha>0$, $\beta>0$ are

Nonoscillatory solutions of planar half-linear differential systems: a Riccati equation approach
In this paper an attempt is made to depict a clear picture of the overall structure of nonoscillatory solutions of the first order half-linear differential system \begin{equation*} x'-p(t)\varphi_{1/\alpha}(y)=0,\qquad y'+q(t)\varphi_{\alpha}(x)=0, \tag{

Hille–Nehari type criteria and conditionally oscillatory half-linear differential equations
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 ...

Oscillation criteria for second order half-linear differential equations with delay [PDF]
The oscillation criteria of different types of differential equations are often the topic of numerous scientific papers, because their application in nuclear physics, fluid mechanics, relativistic mechanics, the study of chemical reactions in the system ...

Variational method and conjugacy criteria for half-linear differential equations [PDF]
The authors analyse the conjugacy of the second order half-linear differential equation \[ -[r(t)\Phi (x')]'+c(t)\Phi (x) = 0, \quad \Phi (x) = |x|^{p-1} \operatorname {sgn}\,x, p>1 \] in the interval \([-a,a], a\in \mathbb {R}\) (\(r,c\) being continuous functions and \(r(t)>0\) for \(t \in [-a,a]\)).
