在最近的一篇预印本(B)中,Bergweiler描述了一个有理映射的多重混合点的直接盆地中包含的临界点的数目:P 1 !p1,吸引花瓣的个数N和残数(f;)1-形式dz=(zf (z)) at。在本文中,我们提出了一种不同的方法来解决同样的问题,这是我们在同一时间独立开发的。我们用我们的方法来回答Bergweiler提出的一个问题。特别地,我们证明了当邻近盆地中只有N个临界点的大轨道等价类时,则N= 2:
In a recent preprint (B), Bergweiler relates the number of critical points contained in the immediate basin of a multiple xed point of a rational mapf :P 1 !P 1 , the number N of attracting petals and the residue (f; ) of the 1-form dz=(z f(z)) at . In this article, we present a dieren t approach to the same problem, which we were developing independently at the same time. We apply our method to answer a question raised by Bergweiler. In particular, we prove that when there are only N grand orbit equivalence classes of critical points in the immediate basin, then N= 2 :
