**Application of dynamical systems to the study of asymptotic properties of solutions to nonlinear higher-order differential equations.**
*(English)*
Zbl 1093.37005

Summary: We study asymptotic properties of a higher-order, nonlinear, Emden-Fowler-type differential equation. We investigate asymptotics of all possible solutions of the equation in the cases of regular and singular nonlinearity for \(n = 3,4\). We use the method of change of variables, which allows one to reduce the initial equation of order \(n\) to a dynamical system on the (\(n - 1\))-dimensional compact sphere.
