Admissible perturbations of Langford system

E. V. Musafirov

Y. Kupala Grodno State University

Abstract: The set of three-dimensional systems of nonautonomous ordinary differential equations for which the reflecting function coincides with reflecting function of the Langford system is obtained. It allows comparing the qualitative behavior of solutions of the obtained systems and Langford system.

Keywords: reflecting function, system of ordinary differential equations, Hopf bifurcation, periodic solution.
