Oscillation criteria for third-order semi-canonical differential equations with unbounded neutral coefficients

open access: yes
In this paper, we investigate the oscillatory behavior of solutions to a class of third-order differential equations of the form Lz(t) + f (t)yβ (σ(t)) = 0, where Lz(t) = (p(t)(q(t)zt(t))t)t is a semi-canonical operator and z(t) = y(t) + g(t)y(τ (t ...

Oscillation results for third order nonlinear delay dynamic equations on time scales

open access: yes, 2011
In this paper, we consider the third order nonlinear delay dynamic equations (a (t) { [ r (t) x ? (t) ] ?} ? ? + f (t,x ( (t) ) ) = 0, on a time scale T, where ?

A Comparison Theorem For Linear Delay Differential Equations

open access: yes, 2007
. In this paper property (A) of the linear delay differential equation Lnu(t) + p(t)u(ø(t)) = 0; is to deduce from the oscillation of a set of the first order delay differential equations.

A Comparison Result and Elliptic Equations Involving Subcritical Exponents

open access: yes, 1992
It is well known that good bounds for solutions of nonlinear differential equations are difficult to obtain. In this paper, we establish a theorem comparing non-negative solutions (having identical initial values) of the equations u 00 (t) + q(t)u p (
