Annotation | A new technique for investigating the stability of nonlinear nonstationary discrete systems, based on the modified direct Lyapunov method and the construction of comparison equations is proposed. The article demonstrates the effectiveness of this technique on the example of non-stationary nonlinear discrete mathematical 3D population model. The search for the global uniform asymptotic stability domain of the system solutions is realized using the Maple mathematical package. The results of numerical simulation are presented. |

Keywords | Stability of nonlinear systems, direct Lyapunov method, comparison system, Volterra nonlinear equation, discrete systems |
