摘要:

证明了时滞Duffing方程$\ddot{x}(t)+x(t-T)+x^3(t)=0$具有无穷无界的快速振荡的渐近稳定的周期解序列,对于固定的时滞使得$T^2<\tfrac{3}{2}π^2$ .与以前的几个涉及近似解的工作相比,这里的处理是精确的。

英文摘要:

The delayed Duffing equation $\ddot{x}(t)+x(t-T)+x^3(t)=0$ is shown to possess an infinite and unbounded sequence of rapidly oscillating, asymptotically stable periodic solutions, for fixed delays such that $T^2<\tfrac{3}{2}π^2$. In contrast to several previous works which involved approximate solutions, the treatment here is exact.
