THE NUMBERS OF PERIODIC SOLUTIONS OF THE POLYNOMIAL DIFFERENTIAL EQUATION
초록
This article deals with the number of periodic solutions of the second order polynomial differential equation using the Riccati equation, and applies the property of the solutions of the Riccati equation to study the property of the solutions of the more complicated differential equations. Many valuable criterions are obtained to determine the number of the periodic solutions of these complex differential equations.
