摘要:

微分方程初值问题全局解的存在性是研究李雅普诺夫意义下稳定性的先决条件。该文旨在研究初值问题(1.10)-(1.11)全局解的存在性.首先得到了初值问题(1.10)-(1.11)局部解的存在性,推广了文献[14]的结果;然后基于得到的延拓定理,证明了初值问题(1.10)-(1.11)全局解的存在性和唯一性.

关键词: 非线性, 分数阶, 存在性, 时滞, 全局解

Abstract:

The existence of global solutions of initial value problems (IVP) for differential equations is a precondition to study their stability in Lyapunov sense. This paper aims to investigate the existence of the global solutions of the IVP (1.10)-(1.11). The existence of a local solution of the IVP (1.10)-(1.11) is obtained first, which is an extension of the paper[14]. Then based on our extension theorem, we prove that the existence and uniqueness of the global solution of the IVP (1.10)-(1.11).

Key words: Nonlinear, Fractional, Existence, Delay, Global solution
