我们注意到,我们的方法并不是经典迭代理论结果的唯一可能推广。Hinkkanen和Martin[4]研究了一类非常亚纯函数S={f1, f2,…}生成的有理半群。当我们说点z∈C∞属于Fatou集合(定义如下)时,如果(Fn)在z的某些邻域中是正态的,Hinkkanen和Martin检验{g1◦…◦gn: gk∈S for k= 1,…, n, n∈n}。
We note that our approach is not the only possible generalization of the classical iteration theory results. Hinkkanen and Martin [4] examine rational semigroups generated by a family of nonconstant meromorphic functions S={f1, f2,...}. While we say that a point z∈ C∞ belongs to the Fatou set (as defined below) if (Fn) is normal in some neighbourhood of z, Hinkkanen and Martin examine the set of normality of {g1◦...◦ gn: gk∈ S for k= 1,..., n, n∈ N}.
