NONEXISTENCE THEOREM EXCEPT THE OUT-OF-PHASE AND IN-PHASE SOLUTIONSIN THE COUPLED VAN DER POL EQUATION SYSTEM

摘要

We consider a coupled van der Pol equation system. Our coupled system consists of two van der Polequations that are connected with each other by linear terms. We assume that two distinctive solutions(out-of-phase and in-phase solutions) exist in the dynamical system of coupled equations and give answersto some problems.
