摘要
证明了一个Halanay型不等式并用它研究了半线性泛函微分方程的Lagrange稳定性.通过利用矩阵测度,以欧基里德空间范数构造简单的李雅普诺夫函数,得到了半线性泛函微分方程关于部分变元为Lagrange稳定的充分条件.在矩阵测度这一框架下统一了数个现有结果.
A new Halanay-type inequality is proved and applied to the study of Lagrange stability for semilinear functional differential equations (FDEs). By using matrix measures, constructed simple Lyapunov functions and obtained verifiable sufficient conditions for the Lagrange stability with respect to partial variables for semilinear FDEs. The results provide a unifying approach to studying the stability of nonlinear FDEs and combine many existing results in a single framework.
