Oscillation criteria for certain fourth order nonlinear functional differential equations
Some new criteria for the oscillation of the fourth order functional differential equation d dt ( 1 a3(t) ( d dt 1 a2(t) ( d dt 1 a1(t) ( d dt x(t) )α1)α2)α3) + δq(t) f (x[g(t)]) = 0, where δ = ±1 are established. c © 2006 Elsevier Ltd. All rights reserved.

متن کاملNew Oscillation Criteria for Fourth-Order Difference Equations
In this work, oscillatory behavior of solutions of a class of fourth order neutral functional difference equations of the form ∆ ( r(n)∆(y(n) + p(n)y(n−m)) ) + q(n)G(y(n− k)) = 0 is studied under the assumption ∞ ∑

This paper is concerned with the oscillatory behavior of the fourth-order nonlinear differential equation (E) (p(t)|x| x)′′ + q(t)|x|x = 0 , where α > 0, β > 0 are constants and p, q : [a,∞) → (0,∞) are continuous functions satisfying conditions
متن کاملSome Oscillation Criteria For First Order Delay Dynamic Equations
We present an oscillation criterion for first order delay dynamic equations on time scales, which contains well-known criteria for delay differential equations and delay difference equations as special cases. We illustrate our results by applying them to various kinds of time scales.
