摘要
本文研究三阶半线性中立型分布时滞微分方程的振动性质.我们同时考虑了正则和非正则两种情况,利用广义Riccati变换和积分平均技巧,建立了在两种情况下保证方程的每一个解振动或者收敛到零的若干新的充分条件,所得定理推广和改进了最近文献中的若干结果.
The objective of this paper is to study the oscillation of a certain of third-order half linear neutral differential equations with distributed delay, where the canonical case and noncanonical case are dealt with.By using a generalized Riccati Transformation and integral averaging technique, we establish some new sufficient conditions which ensure that every solution of this equation oscillates or converges to zero. The theorems obtained generalize and improve known results in the literature recently.
