А.V. Lasunsky. Maintaining steady-state equilibrium after discretization of the system // Transactions of Karelian Research Centre of Russian Academy of Science. No 4. Mathematical Modeling and Information Technologies. 2014. Pp. 87-92

Keywords: preservation of stability after discretization, Lyapunov's first method, nonautonomous Lotka-Volterra model

With the help of Lyapunov's first method we obtained sufficient conditions for maintaining the equilibrium state and its asymptotic stability after discretization of a nonautonomous system of second order differential equations. The result is illustrated by a modified Lotka-Volterra model in which part of the prey population is inaccessible for the predator.
