Title: Non-existence theorem of periodic solutions except out-of-phase and in-phase solutions in the coupled van der Pol equation system.
ABSTRACT:
We consider the periodic solutions of the coupled van der Pol equation system $\Sigma$, which is quite different from the ordinary van der Pol equation. We show the necessary and sufficient condition for the periodic solutions of $\Sigma$. Non-existence theorem of periodic solutions except out-of-phase and in-phase solutions in $\Sigma$ is presented.
