Autonomous Noether boundary-value problems not solved with respect to the derivative
S. M. Chujko, O. V. Nesmelova (Starkova) Donbass State Pedagogical University
Abstract:
In monographs of N. V. Azbelev, A. M. Samoilenko, and A. A. Boichuk, constructive methods of the study of Noether boundary-value problems have been developed. These methods continue the investigation of periodic problems stated by H. Poincaré, A. M. Lyapunov,
N. M. Krylov, N. N. Bogolyubov, I. G. Malkin, and O. Veivoda by methods of small parameter. We propose an improved scheme of the study of autonomous Noether boundary-value problems for nonlinear systems in critical cases. In the case of multiple roots of the equation for generating constants, we obtain sufficient conditions of the existence of solutions to an autonomous boundary-value problem not solved with respect to the derivative. The effectiveness of the scheme proposed is illustrated by an example of the periodic problem for the Liénard equation.
Keywords:
autonomous boundary-value problem, ordinary differential equation, Liénard equation.
