摘要
研究了一类含分布时滞与阻尼项的三阶非线性泛函微分方程[r(t)x″(t)]'+p(t)x'(t)+∫baq(t,ξ)f(x(σ(t,ξ)))dξ=0,利用广义Riccati变换和H函数技巧,建立了保证此方程一切解Philos型振动或者收敛到零的若干新的充分条件。
The oscillation of third-order nonlinear neutral functional differential equations with distributed delays and damped terms is studied. By using a generalized Riccati transformation and H-functions technique, some new sufficient conditions which insure that any solution of this equation Philos-type oscillation or converges to zero are established.
