具有可数无限个不定常时滞的非线性抽象发展方程的指数衰减

Exponential decay for nonlinear abstract evolution equations with a countably infinite number of time-dependent time delays

Alessandro Paolucci

摘要:

本文研究了一类具有无穷多个不定常时滞和Lipschitz连续非线性项的非线性抽象发展方程。利用一个不动点证明了该方程的一个温和解的存在性。这使得我们也可以考虑非负时滞。此外,利用Gronwall估计,在对系统中出现的参数和初始数据的一些小的假设下,证明了解的指数衰减性。最后举例说明。

英文摘要:

In this paper we analyze a nonlinear abstract evolution equation with an infinite number of time-dependent time delays and a Lipschitz continuous nonlinear term. By using a fixed point argument we prove the existence of a mild solution. This allows us to take into account also nonnegative time delays. Furthermore, by using Gronwall estimates, exponential decay of the solution is also proved under some smallness assumptions on the parameters appearing in the system and on the initial data. Finally some examples are illustrated.
