Using the Lyapunov Krasovskiˇi functionals (LKFs), new and improved Lyapunov-Krasovskiˇi type fundamental criteria of uniformly stability (US), uniformly asymptotically stability (UAS), integrability and boundedness of solutions are obtained, respectively. Here, four new theorems are presented as complements of some related results in the past literature. Finally, we verify our results by giving two numerical examples with plots of paths of solutions. © CSP - Cambridge, UK; I&S - Florida, USA, 2022eninfo:eu-repo/semantics/closedAccessBoundednessIntegrabilityLkfMultiple Constant DelaysSystem Of DdesUasUsArticle291N/AQ4289302
