摘要

This paper studies the stability of Caputo fractional linear time-varying systems through an integral equation framework. Using the Volterra representation of solutions, we derive sufficient conditions for uniform Mittag–Leffler stability based on fractional integral inequalities and comparison principles. The approach avoids the use of non-valid Leibniz rules and yields explicit solution bounds in terms of Mittag–Leffler functions. Analytical examples illustrate the theoretical results.
