Oscillation theorems for certain third order nonlinear delay dynamic equations on time scales
Electronic Journal of Qualitative Theory of Differential Equations, 2011 In this paper, we establish some new oscillation criteria for the third order nonlinear delay dynamic equations $$\left(b(t)\left([a(t)(x^\Delta(t))^{\alpha_1}]^\Delta\right)^{\alpha_2}\right)^\Delta+q(t)x^{\alpha_3}(\tau(t))=0$$ on a time scale $\mathbb{

Oscillation criteria for third order delay nonlinear differential equations
Electronic Journal of Qualitative Theory of Differential Equations, 2012 The purpose of this paper is to give oscillation criteria for the third order delay nonlinear differential equation \begin{equation*} \lbrack a_{2}(t)\{(a_{1}(t)(x^{\prime }(t))^{\alpha _{1}})^{\prime}\}^{\alpha _{2}}]^{\prime }+q(t)f(x(g(t)))=0, \end ...

Oscillation criteria for second order nonlinear neutral differential equations of mixed type
Electronic Journal of Qualitative Theory of Differential Equations, 2012 Some oscillation criteria are established for the second order nonlinear neutral differential equations of the form \begin{equation*} \left( \left( x(t)+a x(t-\tau_1)-b x(t+\tau_2)\right)^\alpha\right)''=q(t) x^\beta (t-\sigma_1)+p(t)x^\beta(t+\sigma_2)

OSCILLATING FILAMENTS. I. OSCILLATION AND GEOMETRICAL FRAGMENTATION [PDF]
The Astrophysical Journal, 2017 ABSTRACT We study the stability of filaments in equilibrium between gravity and internal as well as external pressure using the grid-based AMR code RAMSES. A homogeneous, straight cylinder below a critical line mass is marginally stable. However, if the cylinder is bent, such as with a slight sinusoidal perturbation, an otherwise stable ...

Oscillatory behavior of the second order noncanonical differential equations
Electronic 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*}
