Global Stability Analysis of the Age-Structured Chemostat With Substrate Dynamics
Iasson Karafyllis, Dionysios Theodosis, Miroslav Krstic
In this paper we study the stability properties of the equilibrium point for an age-structured chemostat model with renewal boundary condition and coupled substrate dynamics under…
Results for Global Attractivity of Interior Equilibrium Points for Lotka-Volterra Systems
Iasson Karafyllis
This paper provides global attractivity results for the interior equilibrium point of a general Lotka-Volterra system with no restriction on the dimension of the system and with no…
Two Results for the Omega Limit Sets of Dynamical Systems
Iasson Karafyllis
This paper provides two results for the omega limit sets of a dynamical system. We show that omega limit sets can be estimated by using functions that satisfy different (and in man…
Converse Lyapunov-Krasovskii Theorems for Systems Described by Neutral Functional Differential Equation in Hale's Form
Pierdomenico Pepe, Iasson Karafyllis
In this paper we show that the existence of a Lyapunov-Krasovskii functional is necessary and sufficient condition for the uniform global asymptotic stability and the global expone…
Stability Results for Systems Described by Coupled Retarded Functional Differential Equations and Functional Difference Equations
Iasson Karafyllis, Pierdomenico Pepe, Zhong-Ping Jiang
In this work stability results for systems described by coupled Retarded Functional Differential Equations (RFDEs) and Functional Difference Equations (FDEs) are presented. The res…
