Conditionally oscillatory linear differential equations with coefficients containing powers of natural logarithm

open access: yesAIMS Mathematics, 2022
In this paper, we study linear differential equations whose coefficients consist of products of powers of natural logarithm and very general continuous functions.

Comparison theorems for oscillation and non-oscillation of perturbed Euler type equations [PDF]

open access: yesOpuscula Mathematica
The aim of this paper is to present two comparison theorems. These results enable to describe the oscillation behavior of second order Euler type half-linear differential equations with perturbations in both terms using previously obtained oscillation ...

Non-oscillation of half-linear differential equations with periodic coefficients

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2015
We consider half-linear Euler type differential equations with general periodic coefficients. It is well-known that these equations are conditionally oscillatory, i.e., there exists a border value given by their coefficients which separates oscillatory ...

Oscillation and non-oscillation criterion for Riemann–Weber type half-linear differential equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2016
By the combination of the modified half-linear Prüfer method and the Riccati technique, we study oscillatory properties of half-linear differential equations.

Oscillation constant for modified Euler type half-linear equations

open access: yesElectronic Journal of Differential Equations, 2015
Applying the modified half-linear Prufer angle, we study oscillation properties of the half-linear differential equation $$ [ r(t) t^{p-1} \Phi(x')]' + \frac{s(t)}{t \log^pt} \Phi(x) = 0, \quad \Phi(x)=|x|^{p-1}\hbox{sgn} x.

Non-oscillation of linear differential equations with coefficients containing powers of natural logarithm

open access: yesOpen Mathematics
We study linear differential equations whose coefficients consist of products of powers of natural logarithm and general continuous functions. We derive conditions that guarantee the non-oscillation of all non-trivial solutions of the treated type of ...

Distribution of the Prufer angle in p-Laplacian eigenvalue problems

open access: yesElectronic Journal of Differential Equations, 2014
The Prufer angle is an effective tool for studying Sturm-Liouville problems and p-Laplacian eigenvalue problems. In this article, we show that for the p-Laplacian eigenvalue problem, when x is irrational in (0,1), a sequence of modified Prufer angles
