ФИЛИППОВ极限环存在定理在一类方程组=Ф(y)-F(x),=-g(x)上的推广
Extension of the Filippov’s Existence Theorem of Limit Cycle to the System=φ(y)-F(x), =-g(x)
【摘要】 本文用文[1]类似的方法,将极限环存在定理推广到更一般的系统=φ(y)-F(x)y=-g(x)中去,得到两个定理,其中定理1包含文[1]中的定理,定理2包含文[3]中的定理1。
【Abstract】 In this paper we use the method similar to that of reference 1 to extend the Fillippov’s existence theorem of limit cycle to the more general system x=φ(y)-F(x), y=-g(x) and we obtain two theorem. The theorem 1 contains the theorem of reference[1], and the theorem 2 contains the theorem 1 of reference[3].
