Oscillatory behavior of the second order noncanonical differential equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2019
Establishing monotonical properties of nonoscillatory solutions we introduce new oscillatory criteria for the second order noncanonical differential equation with delay/advanced argument \begin{equation*} (r(t)y'(t))'+p(t)y(\tau(t))=0. \end{equation*}

Variational method and conjugacy criteria for half-linear differential equations [PDF]

open access: yes, 2013
summary:We establish new conjugacy criteria for half-linear second order differential equations. These criteria are based on the relationship between conjugacy of the investigated equation and nonpositivity of the associated energy ...

Delay-dependent exponential stability of neutral stochastic delay systems [PDF]

open access: yes, 2009
This paper studies stability of neutral stochastic delay systems by linear matrix inequality (LMI) approach. Delay dependent criterion for exponential stability is presented and numerical examples are conducted to verify the effectiveness of the proposed

Analysis and numerical solution of a non-standard non-linear integro-differential boundary value problem [PDF]

open access: yes, 2011
The aim of this thesis is the analytical study and the development of a numerical method to solve a non-linear, integro-differential boundary value problem on the half line which is representative of a class of non-standard integral equations where the ...

Collocation schemes for periodic solutions of neutral delay differential equations [PDF]

open access: yes, 2005
We introduce two collocation schemes for the computation of periodic solutions of neutral delay differential equations (NDDEs): one based on a direct discretisation of the underlying NDDE, and one based on a discretisation of a related delay differential

Remarks on the existence of nonoscillatory solutions of half-linear ordinary differential equations, II [PDF]

open access: yes, 2021
summary:We consider the half-linear differential equation of the form \[ (p(t)|x^{\prime }|^{\alpha }\mathrm{sgn}\,x^{\prime })^{\prime } + q(t)|x|^{\alpha }\mathrm{sgn}\,x = 0\,, \quad t \ge t_{0} \,, \] under the assumption that $p(t)^{-1/\alpha }$ is ...

Oscillation results for second order half-linear neutral delay differential equations with "maxima"

open access: yesTamkang Journal of Mathematics, 2017
In this paper, we present some oscillation criteria for the second order half-linear neutral delay differential equation with ``maxima" of the from\begin{equation*}\left(r(t)((x(t)+p(t)x(\tau(t)))')^{\alpha}\right)'+q(t) \max_{[\sigma(t),\;t]}x^{\alpha}(s)=0\end{equation*}under the condition $\int_{t_0}^{\infty}\frac{1}{r^{1/ \alpha}(t)}dt<\infty ...
