Oscillation Theorems for Even Order Neutral Equations with Continuous Distributed Deviating Arguments
نویسندگان
چکیده
A class of even order neutral equations with continuous distributed deviating arguments [x(t) + ∫ d c p(t, η)x[r(t, η)]dτ(η)] + ∫ b a q(t, ξ)f(x[g(t, ξ)])dσ(ξ) = 0 is considered and its oscillation theorems are discussed. These theorems are of higher degree of generality and deal with the cases which are not covered by the known criteria. Particularly, these criteria extend and unify a number of existing results.

Oscillation of Solutions to a Higher-order Neutral Pde with Distributed Deviating Arguments
This article presents conditions for the oscillation of solutions to neutral partial differential equations. The order of these equations can be even or odd, and the deviating arguments can be distributed over an interval. We also extend our results to a nonlinear equation and to a system of equations.
متن کاملOscillation Criteria for Damping Quasi-Linear Neutral Differential Equations with Distributed Deviating Arguments
In this paper, we investigate the oscillation criteria for damp quasi-linear neutral differential equations with distributed deviating arguments. By using the generalized Riccati transformation and integral averaging, several new criteria that ensure the oscillation of solutions are obtained. Our results not only include some previously known results, but apply to some damped differential equat...
