Here, for the considered systems, easily verifiable and applicable uniformly asymptotic stability, integrability, and boundedness criteria are obtained via defining an appropriate Lyapunov-Krasovskii functional (LKF) and using the Lyapunov-Krasovskii method (LKM). Comparisons with a former result that can be found in the literature illustrate the novelty of the stability theorem and show new contributions to the qualitative theory of solutions. A discussion of two illustrative examples and the obtained results are presented.eninfo:eu-repo/semantics/openAccessSystem Of DdesUniformly Asymptotically StabilityIntegrabilityBoundedness At InfinityLyapunov-Krasovskii FunctionalMultiple Time-Varying DelayArticle103Q2N/AWOS:000699295900001
