ON CONNECTED HALF-LINEAR DIFFERENTIAL EQUATIONS

open access: yesDemonstratio Mathematica, 1999
Summary: Relations among several classes of half-linear differential equations with or without delays are established. By means of these connections, the existence of eventually positive solutions can be inferred from the properties of either one of these families of equations.

Nonoscillation of higher order half-linear differential equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2015
We establish nonoscillation criteria for even order half-linear differential equations. The principal tool we use is the Wirtinger type inequality combined with various perturbation techniques.

A precise asymptotic description of half‐linear differential equations

open access: yesMathematische Nachrichten, 2023
AbstractWe study asymptotic behavior of solutions of nonoscillatory second‐order half‐linear differential equations. We give (in some sense optimal) conditions that guarantee generalized regular variation of all solutions, where no sign condition on the potential is assumed.

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 ...

Oscillations of Third Order Half Linear Neutral Differential Equations

open access: yesمجلة بغداد للعلوم, 2015
In this paper the oscillation criterion was investigated for all solutions of the third-order half linear neutral differential equations. Some necessary and sufficient conditions are established for every solution of (a(t)[(x(t)±p(t)x(?(t) ) )^'' ]^? )^'+

Even Order Half-Linear Differential Equations with Regularly Varying Coefficients

open access: yesMathematics, 2020
We establish nonoscillation criterion for the even order half-linear differential equation (−1)nfn(t)Φx(n)(n)+∑l=1n(−1)n−lβn−lfn−l(t)Φx(n−l)(n−l)=0, where β0,β1,…,βn−1 are real numbers, n∈N, Φ(s)=sp−1sgns for s∈R, p∈(1,∞) and fn−l is a regularly varying (

Hille-Nehari type oscillation and nonoscillation criteria for linear and half-linear differential equations [PDF]

open access: yesMATEC Web of Conferences, 2019
Differential equations attract considerable attention in many applications. In particular, it was found out that half-linear differential equations behave in many aspects very similar to that in linear case. The aim of this contribution is to investigate
