解釋
遞歸定理-
In the last chapter, by introducing the isochronous center of real systems into complex planar and defining complex center and complex isochronous center, a concise linear recursion formula for period constants is given, necessary and sufficient conditions of complex isochronous center ( the time - angle difference theorem ) proved, conditions of real systems with linearizable center and saddle treated unitedly and the isochronous center conditions discussed fully for a class of real planar cubic systems
在第七章,通過把實系統等時中心引入復平面研究,定義了復中心和復等時中心,給出了等時中心周期常數計算的簡明的線性遞推公式,證明了等時中心判定的充分必要條件(時角差定理人統一地處理了實系統具有可線性化的中心和鞍點條件,並對一類實平面三次系統的等時中心條件進行了完整研究
