Stability of discrete-delay systems: Boundary criteria. (English) Zbl 0874.93084
The stability problem is discussed for linear discrete-delay systems. Two sufficient stability conditions are derived using the maximum principle of harmonic functions. It is shown that they lead to improvement over some existing results.
