New methods for the investigation of periodic solutions in ring systems of unidirectionally coupled oscillators

摘要

We consider special systems of ordinary differential equations, namely, the so-called ring chains of unidirectionally coupled oscillators. A new method is developed for the investigation of the problems of existence and stability of periodic solutions for this class of systems. As a specific feature of this approach, we can mention the use of certain auxiliary delay systems for the determination of cycles and the analysis of their properties. The proposed method is illustrated by a specific example.
