Nonoscillation Criteria for Solutions of Higher-order Functional Difference Equations of Neutral Type
In this paper, we find necessary conditions for every solution of the neutral functional difference equation ∆m−1 ( rn∆(yn − pnyτ(n)) ) + qnG(yσ(n)) = fn to oscillate or to tend to zero as n→∞, where ∆ is the forward difference operator, given by ∆xn = xn+1−xn; and pn, qn, rn are sequences of real numbers with qn ≥ 0, rn > 0. It is supposed that τ(n) and σ(n) are increasing sequences of integer...

In this article, we establish oscillation criteria for all solutions to the neutral differential equations [x(t)± ax(t± h)± bx(t± g)] = p Z d
متن کاملOscillation of certain higher-order neutral partial functional differential equations.
In this paper, we study the oscillation of certain higher-order neutral partial functional differential equations with the Robin boundary conditions. Some oscillation criteria are established. Two examples are given to illustrate the main results in the end of this paper.
متن کاملKamenev-Type Oscillation Criteria for Higher-Order Neutral Delay Dynamic Equations
In this paper, we are primarily concerned with the oscillation of solutions to higher-order dynamic equations. We first extend some recent results which have been obtained for second-order dynamic equations to even-order neutral delay dynamic equations. Our technique depends on making use of the Riccati substitution and the use of properties of the generalized Taylor monomials on time scales. W...
