On stability of solutions to one class of nonlinear difference systems

Abstract: We consider some class of systems of nonlinear ordinary differential equations. We adjust the difference schemes corresponding to the equations under study in order to guarantee agreement between differential and difference systems in the sense of stability of the zero solution. We obtain conditions under which perturbations do not violate the asymptotic stability of solutions to difference systems.

Keywords: stability of difference systems, Lyapunov function, conservative numerical methods, stability in nonlinear approximation.
