摘要

为拓展整数阶微分系统的已有结果,研究了 一类具有多个时滞的Caputo分数阶线性微分系统.运用不可交换矩阵的多项式定理,在不要求系数矩阵可交换的前提下,得到了系统的精确解表示.研究结果表明,该系统在有限时间内Hyers-Ulam稳定.

Abstract

To extend the existing results of differential systems of integer order,we have considered a class of Caputo fractional linear differential systems with multiple delays.By applying the multinomial theorem for nonpermutable matrices without a commutativity assumption on the matrix coefficients,the representations of exact solutions for the studied systems were obtained.The results show that Hyers-Ulam stability in finite time holds for this class of systems.
