Interval Oscillation Criteria for Super-Half-Linear Impulsive Differential Equations with Delay

Journal of Applied Mathematics, 2012
We study the following second-order super-half-linear impulsive differential equations with delay [r(t)φγ(x′(t))]′+p(t)φγ(x(t-σ))+q(t)f(x(t-σ))=e(t), t≠τk, x(t+)=akx(t), x′(t+)=bkx′(t), t=τk, where t≥t0∈ℝ, φ*(u)=|u|*-1u, σ is a ...

Iterative Kneser-Type Criteria for Oscillation of Half-Linear Second-Order Advanced Dynamic Equations

Mathematics
This work aims to develop new iterative Kneser-type criteria for determining the oscillatory behaviour of half-linear second-order advanced dynamic equations on arbitrary unbounded-above time scales T. The results extend and refine previously established

Oscillation of solutions to third-order half-linear neutral differential equations

Electronic Journal of Differential Equations, 2012
In this article, we study the oscillation of solutions to the third-order neutral differential equations $$ Big(a(t)ig([x(t)pm p(t)x(delta(t))]''ig)^alphaBig)' + q(t)x^alpha(au(t)) = 0.

Non-oscillation of periodic half-linear equations in the critical case

Electronic Journal of Differential Equations, 2016
Recently, it was shown that the Euler type half-linear differential equations $$ [ r (t) t^{p-1}\Phi(x')]' + \frac{s (t)}{ t \log^p t} \Phi(x) = 0 $$ with periodic coefficients r and s are conditionally oscillatory and the critical oscillation ...

Oscillation criteria for damped quasilinear second-order elliptic equations

Electronic Journal of Differential Equations, 2011
In 2010, Yoshida [13] stated that oscillation criteria for the superlinear-sublinear elliptic equation equation $$ abla cdot ig(A(x)Phi(abla v)ig) + (alpha+1)B(x)cdotPhi(abla v) + C(x) phi_eta(v) + D(x) phi_gamma (v)=f(x) $$ were not known.

Linearized Riccati Technique and (Non-)Oscillation Criteria for Half-Linear Difference Equations

Advances in Difference Equations, 2008
We consider the half-linear second-order difference equation , , , where , are real-valued sequences. We associate with the above-mentioned equation a linear second-order difference equation and we show that oscillatory properties of the above ...
