Nonoscillation of Second Order Superlinear Differential Equations

Canadian Mathematical Bulletin, 1994
AbstractSome sufficient conditions are given for all solutions of the nonlinear differential equation y″(x) +p(x)f(y) = 0 to be nonoscillatory, where p is positive andfor a quotient γ of odd positive integers, γ > 1.

Nonoscillation in half-linear differential equations

Publicationes Mathematicae Debrecen, 1996
Necessary conditions are given for the nonoscillation of the solutions of the equation \[ [r(t)|u'(t)|^{p-2}u'(t)]'+c(t)|u(t)|^{p-2}u(t)=0, \] where \(p>1\) is a constant, and \(r(t)>0\).

Maximum Principles and Nonoscillation Intervals

2012
In the previous chapters, as well as in the known monographs on nonoscillation of functional differential equations, nonoscillation was only interpreted as existence of eventually positive solutions. In this and the following two chapters, nonoscillation on an interval is considered.

Nonoscillation Characterizations of Second Order Linear Differential Equations

Mathematische Nachrichten, 2000
The author studies a nonoscillatory feature of the linear differential equation \((pu')'+qu=0\), which is equivalent to the identical feature of any related, similar equation \((PU')'+QU=0\), or the solvability of the corresponding nonlinear differential inequality \(V'+V^2/P+Q\leq 0\).

A NONOSCILLATION THEOREM FOR SUBLINEAR EMDEN-FOWLER EQUATIONS

Analysis and Applications, 2003
Consider the Emden-Fowler equation (E) : y″ + a(x)|y|γ-1y = 0, where γ > 0 and a(x) is a positive continuous function on (0, ∞). I. T. Kiguradze showed in 1962 that if x(γ+3)/2+δa(x) is nonincreasing for any δ > 0, then equation (E) is nonoscillatory when γ > 1.
