ON COUPLED VAN DER POL EQUATIONS

摘要

The paper is concerned with coupled Van der Pol equations. The case of two coupled equations is discussed in detail. The case ofNcoupled equations is discussed for some special values of the parameters. It is shown that in a certain parameter domain the solution will for large values of time approach a limit cycle for all initial conditions. The case ofNcoupled equations is also briefly discussed in the Appendix.
